Media: movies opened in place keep their orientation (#796 × #827)

Opening movies in place (#796) skipped the whole-file bytes #827 read the
track matrix from, so the pool and the probe lost the turn for movies on
disk. stream::movie_header reads just the ftyp and moov boxes (bounded,
positional reads) and both in-place paths derive the orientation from it.
