Mass rebuild downgrades

[Bruno Wolff III]

The mass rebuild resulted in some downgrades of things where master was
behind f15 or f16 but hadn't had an f17 build. After the mass rebuild
the rawhide version ended up being lower than the previously inherited
version. These will cause update issues later and possibly may have
other issues if the older sources has bugs that were fixed in F15 or F16.

I didn't do a systematic check for these, but rather these are ones I noticed
after finally getting the update after the mass rebuild done on my rawhide
machine.

The following is yum distro-sync output pointing out the packages with this
issue that I have installed.
