avformat/mov: avss box should be AV_CODEC_ID_CAVS

I cannot find the spec, but according to the original commit
d4fdba0df71, it's CAVS. e571305a714 changed it to AVS by
accident. Ten years on, nothing happened. We still have the
sample [1], however, since there is no cavs_mp4tofoobar bsf, the
cavs decoder doesn't work. I don't know if there is any use case.
