lavc audio enc: improved error reporting

Browse Source 
- print error if:

    1. `uv -s testcard -A Opus --param audio-lavc-encoder=nonsense`
    2. `uv -s testcard -A Opus --param audio-lavc-encoder=libopus` but libopus
was not compiled in

- print requested encoder name if not suitable to encode the codec,
eg. `uv -t testcard -A Opus --param audio-lavc-encoder=AAC`
