- Migrate u-a data from /var/lib/rpm instead of relying on dbpath:
  no u-a version ever installed files explicitly into dbpath, but
  always hard specified /var/lib/rpm. The fact that RPM moved its
  database is irrelevant to update-alternatives. In case RPM moved
  it's database, our files are still accessible via the
  /var/lib/rpm symlink being put in place.
- Drop the arbitrary depenency on a specific rpm version: the idea
  was to ensure to have an rpm with the new dbpath location in
  place. For one, the dependency does not work as intended, and
  2nd, as the migration now happens explicitly from the old u-a
  admindir without relying on dbpath, is no longer needed.
