createrepo in koji also uses the --update flag if a previous repo
exists.  This causes it to parse the existing repodata and reuse it for
all packages that haven't changed.  This is a *huge* increase in speed,
since only 1 or 2 packages have changed between repo regens in the
normal case.

I'm not sure if --update will work with sqlite database, but if not, I'd
like to see that support added before changing the createrepo call.
