python: packetize some python modules

Packetize some Python modules to reduce size of the overall Python package.
Basically, a new package is introduced, call `python-light`,
and everything that's extra (or big) is put in other packages.

The `python` package becomes a metapackage that installs `python-light`
along with the rest of the packages.

Base work started by Jan Čermák.
