lavf/segment: do not copy codec_tag when not available
Some muxers do not allow stream if codec_tag is incompatible.
Sometimes the passed input codec's codec_tag is not compatible with the
output muxer.
Because the codec_tag field of the segment muxer cannot be set, ffmpeg.c
doesn't know how to handle these cases.
