The stricter checks imposed by commit
ac39b313, while being valid in general,
require that media source attaches to media types the attributes that
application can request.

This patch exposes the MF_MT_ALL_SAMPLES_INDEPENDENT attribute to audio
streams (similarly to what is already done for video streams), which is
for example requested by The Medium.
