encode: fix expected streams when using --lavfi-complex 

mpctx->current_track[0][STREAM_VIDEO] (and STREAM_AUDIO) are empty when
using --lavfi-complex. Moving the muxer stream hinting after audio/video chain
initialization and checking if the chains exist fixes encoding with --lavfi-complex.

Previously, the output audio/video streams did not get prepared and the encode
would fail due to unexpected stream addition.
