simple patch

The ffmpeg audio decoders set the channel-positions field in their caps in the
basic mono and stereo cases, which causes caps nego problems when you mix
ffdec-decoded audio with audio from other sources, which don't do this.  The
main place this shows up, for me at least, is in rhythmbox with crossfading
enabled.  See also bug 476370, where faad previously did the same thing.
