Patch to correct MPEG-TS detection logic in Typefind

The current TS detection logic in Typefind checks for the adaptation control
field to be Non-Null to declare the TS as valid TS.
However, there are TS files where adaptation control field is 0 for the packets
with NULL pids.

To resolve this an additional condition is needed that, if adapation control
field is 0 and PID is NULL, then declare as a valid TS stream.

Attaching the patch that is based on above suggestion.
