pkg_resources has been dropped from setuptools v82.0 and newer,
so our setup.py script is currently failing there, breaking our CI.
To fix it, switch to a direct version check instead.
While we're at it, also bump the minimum version of setuptools
to v44 now since that is the minimum that might still be in use
on the distros we care about according to:
 https://repology.org/project/python%3Asetuptools/versions

 No clue whether that version check is fine with all versions of
 setuptools, thus I marked the patch as RFC. At least it survives
 the CI:

This works so:

Reviewed-by: Daniel P. Berrangé <berrange@redhat.com>


but the other option discussed on IRC was to remove the
existing version check entirely on the basis that all our
supported platforms will have sufficient version by default
and we don't need to spend time checking for the benefit of
unsupported platforms.
