Subject: [PATCH 1/2] moltenvk: fix Hydra build failures

MoltenVK requires Xcode to build until a newer SDK (11+) is available in
nixpkgs. Disable building on Hydra until that changes.

Subject: [PATCH 2/2] wine-packages: fix Hydra build failures on Darwin

Disable Vulkan and VKD3D by default on Darwin while MoltenVK is forced
to build using Xcode instead of the SDK in nixpkgs. They can be
overriden if the user needs either of those.
