ffmpeg-headless: disable cuda-llvm support on Darwin

Browse source 
After https://github.com/NixOS/nixpkgs/pull/518519, Clang is unwrapped
when cuda-llvm support is enabled when building ffmpeg. This causes
ffmpeg-headless to fail to build on Darwin because its `configure`
script cannot find dependencies due to using an unwrapped compiler.
Since Cuda isn’t supported on Darwin anyway, disabling cuda-llvm has the
effect of using a wrapped Clang on Darwin again.
