Update the update_package_info script to include other releases than raw...

...hide

Some packages in pkgdb are actually only active in EPEL and have been
dropped from rawhide while still being present in other active branch
of Fedora. So by checking more than just rawhide we should be able to
update the information about most if not all packages in pkgdb.

We are careful though that information coming from rawhide do not get
overridden by older branches.
Are you checking for rawhide here?  If so, that is non-obvious to a reader.

Maybe change VERSIONS to an OrderedDict or list of tuples so that things are explicitly named.  And here you could check if ``name == 'rawhide'``
