mov: move stsd finalization to an appropriate place

mov_finalize_stsd_codec parses stream information from the ALAC extradata,
so run it after the extradata processing is completed in mov_read_stsd.

Fixes playback of 96kHz ALAC streams muxed by qaac or the reference alac encoder.
Fixes trac ticket #5826
