ao: use 16 bit sample format

Browse Source 
There have been bug reports on MPD regarding 24 bit output via
libao/esd.  The "ao" plugin does not attempt fall back to 16 bit
currently, and thus fails to play 24 bit audio (i.e. all mp3 files).
Make it always use 16 bit samples for now, until more bits are
well-tested.
