Fix #3767: RTMP: Do not response empty data packet. v6.0.153 (#4162)

If SRS responds with this empty data packet, FFmpeg will receive an empty stream, like `Stream #0:0: Data: none` in following logs: ```bash ffmpeg -i rtmp://localhost:11935/live/livestream ``` This won't cause the player to fail, but it will inconvenience the user significantly. It may also cause FFmpeg slower to analysis the stream, see #3767 --------- Co-authored-by: Jacob Su <[email protected]>
