[media] bttv: remove g/s_audio since there is only one audio input
Note that the current driver does not implement enumaudio (so apps cannot tell that audio inputs are present), it does not set V4L2_CAP_AUDIO, nor does it set audioset when calling ENUM_INPUT. And G_AUDIO doesn't set the stereo flag either. So these g/s_audio ioctls are quite pointless and misleading. Especially since some surveillance boards do not have audio at all.
