James Almer bc01061231 avformat/movenc: fix writing dOps atoms ...

Don't blindly copy all bytes in extradata past ChannelMappingFamily. Instead
check if ChannelMappingFamily is not 0 and then only write the correct amount
of bytes from ChannelMappingTable, as defined in the spec[1].

Fixes part of ticket #9190.
