avformat/movenc: limit ISOBMFF AC-3 mapping to bsids <=8
This leaves out RealAudio DolbyNet, which utilizes bsids 9 and 10,
It is not clear whether the interpreted bit rate value (divided by
2 or 4 depending on the variant), or the original bit rate value
should be utilized to receive the bit_rate_code index.
