jellyfin-ffmpeg: use regular ffmpeg

NixOS#271863

jellyfin-ffmpeg is a rebuild anyways, so we can simply cherry-pick the features
that we actually need rather than smashing ffmpeg-full into it.

These should be all the "special" features jellyfin expects of it.

nvcodec and amf support are already enabled by default in regular ffmpeg.
