[meta-oe][PATCH 30/31] mpv: propagate ffmpeg's commercial LICENSE_FLAGS

mpv has an unconditional DEPENDS on ffmpeg, which carries
LICENSE_FLAGS = "commercial". When "commercial" is not in
LICENSE_FLAGS_ACCEPTED (the default), ffmpeg is skipped, and parsing the
universe target - which, unlike world, ignores EXCLUDE_FROM_WORLD -
reports mpv as an unbuildable dependency chain:

  WARNING: Nothing PROVIDES 'ffmpeg' (but .../mpv_0.41.0.bb DEPENDS on
           or otherwise requires it)
  ffmpeg was skipped: Has a restricted license 'commercial' ...
  NOTE: Runtime target 'mpv' is unbuildable, removing...

Since mpv cannot be built or shipped without accepting ffmpeg's terms,
propagate the flag onto mpv itself. bitbake then skips mpv cleanly (in
both world and universe) with the same "restricted license" note as
ffmpeg, and no longer emits the confusing unbuildable-dependency
warnings. This mirrors how oe-core's gstreamer1.0-libav (which also
DEPENDS on ffmpeg) carries LICENSE_FLAGS = "commercial".

The explicit EXCLUDE_FROM_WORLD is now redundant - a recipe skipped for
its license flags is already excluded from world - so drop it.
