command: add demuxer-lavf-list property

Was only available with --demuxer-lavf-format=help and the demuxer
needed to be used for it to actually print the list.

This can be used in the future to check if 'dash' support was compiled
with FFmpeg so ytdl_hook can use it instead. For now, dashdec is too
rudimentary to be used right away.
