repo-add: clean up options parsing

-f/--force has been dead for a while, so kill it off. In addition, the
check for > 2 args is pretty useless when you do something like:
  repo-add -q -q
or a more legit:
  repo-add -q /path/to/mine.db.tar.gz

So instead make repo-add just return 1 when it doesn't do anything with
the database which seems to make more sense.
