avcodec/mpeg4videoenc: Remove no-output code

While it offers modest speedups compared to the ordinary code,
removing it completely offers even bigger speedups; and given
that these speedups also exist in the ordinary mode, they are
even more important. The no-output code has a 7.8% performance
improvement (based on benchmarking mpeg4_encode_mb()), yet
removing the no-output code resulted in a 9.4% improvement.

Furthermore, the no-output code was broken for the majority of
its existence (until 9207dc3b0db368bb9cf5eb295cbc1129c2975e31)
and no one complained, so it is likely not used at all.
