Attempt to fix .deb package

After recent switch to legacy python2 .deb fails on OBS. Let's put
known-to-work python3 dependency back but keep the script itself on
python without version specifier as it seems to work fine with both
versions.

This, in turn, causes tests to fail on FreeBSD so disable them for now.
