fakesink: use g_object_notify_by_pspec() and remove work-around for old GLib versions if possible

Browse source 
Use more efficient g_object_notify_by_pspec() if we're compiling against
GLib >= 2.26, and also remove work-around for g_object_notify() thread-
safety issues with older GLib versions if it's not needed any more.
