vorbisenc: push an updated segment stop time when we know it
...
When encoding, libvorbis will tell us how many samples are encoded
in the buffer it returns. This number may be less than the maximum
of samples in the block, if this is the last packet. In we have no
segment end time, we set it to the end time of that last sample to
tell downstream that the buffer contains less samples.

Samples may be clipped at the end, and this is conveyed by a
