Fix #3767: RTMP: Do not response empty data packet. v6.0.153 v7.0.12 (#4162)

Browse source 
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
#  Stream #0:0: Data: none
#  Stream #0:1: Audio: aac (LC), 44100 Hz, stereo, fltp, 30 kb/s
#  Stream #0:2: Video: h264 (High), yuv420p(progressive), 768x320 [SAR 1:1 DAR 12:5], 212 kb/s, 25 fps, 25 tbr, 1k tbn
```

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
