dxvk: rely on the cross support in nixpkgs

The `isCross` check is broken. When cross-compiling, it incorrectly
evaluates to false. DXVK has been building using the Meson
cross-compilation support in nixpkgs instead of with upstream’s cross
file. Instead of fixing `isCross`, just drop it as unnecessary.
