movdec: handle 0x7fff langcode as macintosh per the specs
The correct point that seperates ISO and MAC language codes is 0x400
according to the current QT spec. Old QT specs did not list where this
seperation is but apparently only defined the meaning of the first 137.
(cherry picked from commit 9e71cc81f3655cacf0f91860fba3043f13b64059)
