jw-build doesn't stop at building software, packaging it afterwards
is also a core feature, so this commit gives the package a better
name.
The commit replaces strings s/jw-build/jw-pkg/ in text files and file
names. Fallout to the functionality is fixed, variable names are left
as they are, though. To be adjusted by later commits.

For requires, provides and conflicts, isolate the bulk of the code in
BaseCmdPkgRelations, then derive CmdPkgConflicts, CmdPkgProvides and
CmdPkgRequires from that class.
