Not overwrite USERGROUP_ENAB on anything but Ubuntu

The nonsense with umask is introduced by Canonical's infinite wisdom:
https://git.launchpad.net/ubuntu/+source/pam/tree/debian/patches/pam_umask_usergroups_from_login.defs.patch?h=ubuntu/noble
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=583958
We don't need to break sensible distributions because of Ubuntu nonsenses
