rpmlib(PayloadIsXz) is needed by foo for F-12 - rpm update needed from buildsys

Hello ! As some may still want to build update for Rawhide, the current rpm version needed to populate rawhide buildroot isn't capable of handling Xz compression. This can be done updating rpm in the buildsys which are running EL5. I've submitted the bug here to help track the issue: http://bugzilla.rpmfusion.org/show_bug.cgi?id=742 At this step, I'm still investigating what need to be done (which version to take).
