doc: fix and clarify libx264 encoding.

tune, fastfirstpass and profile are not available through x264opts.
Since some FFmpeg options don't match the names used in libx264, add
libx264 option names as a reference when needed. And last thing, x264
don't have a manpage ATM, so prefer the x264 --fullhelp over the
unexistant manpage reference.
