avformat/oggenc: ignore empty packets 

Some encoders, like flac, can send side data only packets at the end.
Eventually, said extradata update should ideally be used to update the header
when writting to seekable output, but for now, ignore them.

Should fix the undefined behavior of passing NULL to memcpy().
