mpegtsmux: add custom AC-3 descriptor

tsdemux expects a custom descriptor (GST_MTS_DESC_AC3_AUDIO_STREAM)
to detect a stream as AC3 and not EAC3.

Note that tsdemux expects this descriptor because mpegtsmux writes
a stream with a HDMV registration descriptor.

Fixes:

gst-launch-1.0 -v audiotestsrc ! avenc_ac3 ! ac3parse ! mpegtsmux ! \
tsdemux ! ac3parse ! avdec_ac3 ! audioconvert ! autoaudiosink
