Fix debian package generation to include subdirectories

[civerachb-cpr]

The existing .deb generation does not include subdirectories, resulting in missing modules:

1. Move package information out of makedeb into setup.py as parameters
2. Explicitly list all python modules that should be included in the package
3. Replace the deb-generation command with python3 setup.py --command-packages=stdeb.command bdist_deb

Tested on Ubuntu 24.04; resulting debian file now includes the missing folders (see screenshot above)

Thanks for your contribution and for trying to improve the Debian package generation.

I don't think we want to proliferate stuff in setup.py. The package has already adopted a more modern approach based on the declarative pyproject.toml file. I have no experience with how Debian usually handles building Python packages, but I doubt that adding stuff to setup.py is state of the art. Of course, neither is an elaborate makedeb script including logic to extract the version string, so there is definitely room for improvment.

Building the package by itself should be left to the PyPA build helper: python3 -m build in the distro's top level directory. Or utilize the common Debian Python package build helpers, such as pybuild.
