Subject: [PATCH] notify: don't depend on any GTK version

If there's one in the process use it. If there's none fallback to
default VLC icon with the old code.

This not only avoids VLC builds depending on GTK, but this should
prevent crashes if GTK 2 is present in the process (e.g. through Qt plugin).
