libavformat/rtpenc_mpegts: check avformat_new_stream() return value
The function avformat_new_stream() returns a NULL pointer on failure.
However, in function rtp_mpegts_write_header(), its return value is not
validated before it is dereferenced. Check the return value against NULL
to avoid potential NULL dereference.
