mgw: accept zero-length RTP payload as BFI
Mainline OsmoBTS now has an option (rtp continuous-streaming)
that causes it to emit an RTP packet every 20 ms without gaps,
sending a BFI marker in the form of zero-length RTP payload
when it has nothing else to send. These codec-independent
BFI markers don't indicate TAF, but this provision is a good
start. Accept this BFI packet format in themwi-mgw.
