Jortel 950036

The fix here is to update our createrepo package to version 0.9.9 using sources from RHEL 6.4.  Although we have deps/createrepo/ in the pulp git repo, we discontinued building it sometime ago.  Also, we switched from using createrepo to using modifyrepo (probably in the same time frame).  These facts lead me to believe that it is safe to upgrade to 0.9.9.  Both RHEL 6.4 and F18 contain 0.9.9 but not 100% sure if the patch set is the same.

The only additional patch to the upstream is:
BZ-950724-compression.patch
Which fixes https://bugzilla.redhat.com/show_bug.cgi?id=950724.

Everything else is noise from updating to 0.9.9.
