Add a function get_profile_env(), a function returning environment
variables from /etc/profile. Pass add=True to add its contents to the
existing environment dictionary, overwriting old entries, or pass
False to get the pristine content.

Add a parameter "output_encoding" to run_cmd(). The parameter allows
the caller to specify if the output encoding should be detected as is
by passing None (the default), if the output should be returned as
undecoded bytes by passing the special string "bytes", or if the
output should be treated as the encoding with the specified name and
decoded to strings.

Don't log an Exception as {e} but as str(e) producing nicer output.
Or as repr(e) if a backtrace is requested, because to people who can
read backtraces, type info might be of interest. Also, remove
pointless time stamps, those belong into the logging framework.

Rename jw.pkg.cmds.distro.backend.BackendCmd to Backend, because it's
not necessarily a command, i.e. doesn't necessarily have a run()
method. It's more of a distribution abstraction of the steps needed
for for a specific command, the run() method itself is implemented in
jw.pkg.cmds.distro.CmdXxx.
This commit is the beginning of a bigger move to change the
distribution backend class hierarchy. At the end of this change set,
the backend command should not derive the backend classes from a base
specific to the respective distribution, but from an abstract base
class specific to the command run. The distribution specifics are
then going to be encapsulated in another class called "Util", an
instance of which is going to be provided to the backend as .util
member.

Move the body of BackendCmd.sudo() into a function. The rationale
behind that is that its functionality is independent of the calling
object for the most part, so having it in a function instead of a
method is the more modular pattern.

apt-get install suggests it wants to be called with -f to clean up
some mess left behind from a previous install. Adding -f in the hope
add it to the install options by default. OTOH, it wants to be called
that without arguments, not sure if always passing it along is a good
idea.
The man page says:
-f, --fix-broken
Fix; attempt to correct a system with broken dependencies in
place. This option, when used with install/remove, can omit any
packages to permit APT to deduce a likely solution. If packages
are specified, these have to completely correct the problem. The
option is sometimes necessary when running APT for the first time;
APT itself does not allow broken package dependencies to exist on
a system. It is possible that a system's dependency structure can
be so corrupt as to require manual intervention (which usually
means using dpkg --remove to eliminate some of the offending
packages). Use of this option together with -m may produce an
error in some situations. Configuration Item:
APT::Get::Fix-Broken.
Also turn the short options -yq into long options --yes --quiet for
more obvious debugging if something goes awry.

CmdGetAuthInfo calls run_cmd() with a list instead of a *-expanded
list of arguments. Fix this to match the current run_cmd() prototype.
And think again if the current prototype conforms to the priciple of
least surprise: Most exec- / run- / whatever- functions do expect
ether a string to be run by the shell, or an argv list.

Prepending --login to the argument list of BackendCmd.sudo() fails if
run as root, because BackendCmd.sudo() detects that and leaves the
/usr/bin/sudo out from the exec call. Fix that by adding an
opts: list[str] parameter to sudo, defaulting to an empty list, with
options that should be passed to /usr/bin/sudo.

Major - but not yet sufficient - code beautification starting from
jw.pkg.App.
- Make more methods private
- Rename methods to be more self-explanatory
- Same for method arguments, notably clean up some inconsistent
uses of "module" vs "project"
- Add more type hints
Fix API breakage in the command modules.

Add a hand-coded __init__.py into jw.pkg.cmds.distro. Auto-generation
