gtk2 and libxml2 need updates

It's quite common practice actually. For example, the whole KDE was updated
to 4.1.3 around the day of the F10 release and we're planning to do the
same with 4.2.3 and F11. Other packages also work that way.

The advantages of pushing stuff as updates on release day:
* it can't break the live images or the installer,
* there are 1-2 extra weeks for testing/fixing (the time between the RC
composes and the first update push),
* it's possible to go through updates-testing (e.g. KDE 4.1.3 went to
updates-testing in the first F10 update push and to the stable updates in
the second).

The drawback is that they don't get included on the live images and the
installer DVD, but need to get updated by the user post-install, but that's
not a big issue for the mingw32-* packages because they aren't on the live
images or the installer DVD anyway, at worst this can affect custom spins
including those packages but not including updates.
