so to make it work in createrepo we'll need:

1. to read the desktop files out of the rpms themselves - that code
exists
2. we'll need to have it work properly with --update so we're not
constantly doing the same thing over and over again on each repo
recreation. - does the code exist to read and break up the xml into
per-desktop-file chunks?

How we do it in the rest of createrepo is we read the existing xml and
prune out those which have been deleted/modified and add those which
have been added/changed.

If that code exists already that makes life quicker to get it into
createrepo.
