Add VP9 as a valid HLS format to enable remuxing. This is useful when audio processing is required, but the VP9 video can be passed as-is to avoid unnecessary video transcoding.
No VP9 encoder is enabled and should not be enabled. AV1 and HEVC should be preferred over VP9 if video transcoding is required.

Apple doesn't support Opus via HLS yet, but if they ever do, they will
definitely expect "Opus" instead of "opus".

I moved the first application of the workaround out of the if block
so that it also applies to audio-only streams. The workaround was
extended likewise.
We should first and foremost adhere to the specifications and apply
workarounds afterwards for software that doesn't follow them. So I
turned around the workaround to first output the fLaC variant and then
the alternative flac variant.
