[apparmor] GTK+ 3

[Michael McConville]

What's the status of the GTK+ and GStreamer abstractions' compatibility
with GTK+ 3 and GStreamer 1.0?

I included them in a profile for Pidgin 3.0, which hasn't been released
yet and uses these newer dep versions. However, it was failing after
trying to access libdc1394, which is associated with GStreamer. Looking
at the abstractions, it seems that only GTK+ 2 and GStreamer 0.1 are
currently supported.
