Subject: stream_ffmpeg, demux_lavf: Use flv demuxer for rtmp streams

Use lavf's flv demuxer for rtmp/rtmps/... stream types. Letting
generic format probing handle this could work, but with the current
probing implementation it'd at least depend on not-really-guaranteed
details of the stream layer (probing different formats and then
decoding depends on seeking back in between; rtmp streams don't
support such seeking directly so would need to rely on details of
caching behavior).
