media-video/obs-studio: add ffmpeg[opus] dependency

With USE="-opus" and without '--disable-encoder=opus' on ffmpeg,
obs-studio still offers to use the Opus encoder and the audio
that is recorded will be mixed with different kinds of noise,
depending somewhat on the bitrate being used.

Closes: https://bugs.gentoo.org/909566
