tsdemux: Handle quirk in jp2k es header handling

The jp2k specification (ITU-T T.800) specifies that the 'brat' box
has two fields and the second one (AUF2) can be set to 0 for progressive
streams.

The problem is that the mpeg-ts specification (ITU-T H.222.0 06/2012)
says that the AUF2 field is only present if the stream is interlaced

In order to cope with both situation, accept those next 32bit if the
stream is marked as progressive and those bits contain 0
