avformat/mpegtsenc: add registration descriptor for AC-3 and EAC3
Some DVB and ATSC captures are using the official MPEG2 registration
descriptor in addition to using the correct stream type and the
AC-3_audio_stream_descriptor/AC3_descriptor. So let's add it even if it is not
strictly needed for DVB/ATSC.
