avformat/mpegtsenc: correct bitstream check 

8559cce3c3 made the bitstream check generic using a LUT.
However, one of the comparisons which involves a bitwise AND
and equality check is faulty due to operator precedence.

First reported and analysed at
https://github.com/streamlink/streamlink/issues/5876

Fixes #10908
