Add IEC958_NONAUDIO output flag to MSD patches

For the formats compatible with IEC61937 encapsulation, assume
that the record thread input from MSD is IEC61937 framed (for
proportional buffer sizing). Add the
AUDIO_OUTPUT_FLAG_IEC958_NONAUDIO flag so downstream HAL can
distinguish between raw and IEC61937 framed streams.
