avformat/libsrt: log streamid in listener mode

Browse Source 
It's useful for test client which pass streamid to ffmpeg/ffplay.
For example, use ffmpeg to test streamid support in VLC:
./ffmpeg -v info -re -i foo.mp4 -c copy -f mpegts -mode listener srt://127.0.0.1:9000
./vlc srt://127.0.0.1:9000?streamid=foobar
