SPECS: Remove Group tags

The Group tag is no longer required:

Furthermore, many of our packages use non-standard groups which
cause rpmlint to complain.   Older versions of rpmlint may complain
about the lack of the Group tag, but this should not cause problems
on modern Fedora or CentOS (>5) systems.
