mpegtsmux: Set the program number from prog-map

Browse source 
The prog-map property of mpegtsmux only allows you to group pids together in a program.
The program number set in the PAT/PMT tables cannot be set explicitly.

This patch will set the program number according to the prog-map.
If a program id of 0 is given, the first vacant program number starting from 1 will be used.
