CmdInfo provides what "projects os-cascade" provided as "distro info
--format '%{cascade}'" plus additional macros: %{id}, %{name},
%{codename} and ${gnu-triplet}.

This is a code maintenance commit: some run_xxx() helper functions
take a string, some a list, and some just digest all arguments and
pass them on as a list to exec() to be executed. That's highly
inconsistent. This commit changes that to list-only.
Except for the run_cmd() method of SSHClient, which is still run as a
shell method, because, erm, it's a shell. Might be changed in the
future for consistency reasons.

Add the distro subcommand class CmdPkg, together with a first
subcommand ls, which prints a list of files contained in a package.

Don't derive the Backend classes from distro-specifiy Util classes
anylonger, but from command-specific BeXxx base classes.

Rename the class Base of all distribution backends to Util. It
contains distribution specifics, but is not going to be the base
class anymore shortly.

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.

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.

Add a hand-coded __init__.py into jw.pkg.cmds.distro. Auto-generation
works fine, but has to run before it can work. For a freshly
downloaded toplevel Makefile / project-dirs-minimal.mk, the targets
pkg-install-xxx-deps requires a working package manager without
jw-pkg built.
