avformat/ffmenc: Drop ffm_write_header_codec_private_ctx()

Browse Source 
This accesses the private encoder context, it should not be used by
the current ffserver it may affect old ffserver versions but i believe
there is consens that accessing the private encoder context from the muxer
is completely wrong.
