[empathy] Remove libempathy-gtk dependency on gstreamer

[Guillaume Desmottes <gdesmott src gnome org>]

commit 6e3ea627e70266d8c3739300e900a5b7bc0763bc
Author: Sjoerd Simons <sjoerd luon net>
Date:   Sun Aug 26 16:20:56 2012 +0200

    Remove libempathy-gtk dependency on gstreamer
    
    libempathy-gtk uses gstreamer directly only for one utility function
    used by empathy-call. Split this one out into a call specific utility
    file.
