Packages up for adoption

[Matthias Clasen]

We plan to drop the standalone gdk-pixbuf and imlib packages from Core
before FC6, together with the rest of the Gnome 1 stack. 

There are probably some things in Extras that still require these,
therefore I put slightly cleaned up spec files and srpms up here:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=194355
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=194353

If anybody feels like maintaining these in Extras, please step up.
