avformat/mpegts: respect program number when merging streams
merge_pmt_versions was not usable if multiple programs were present because when it was searching for candidate streams it did not make sure that the PMT was of the same program. This caused the streams of all programs to get merged into a single (garbled) program. This patch makes sure that the program number (service ID) is also matching with the old streams when parsing the PMT making the feature useful for multi program streams. This change might cause issues for single program streams if the program number changes, but I think it is acceptable because the goal of the option is to make the parsing resilient to PID changes, and that is still working as expected.
