zink: Simplify MoltenVK support a bit

Browse source 
There's no harm in checking for the extension on non-macOS, just do it.
Nor can I see any point in checking for both the layer and the
extension, since you're never going to see the extension if the layer
isn't available, so just check for the extension instead of the reduced
boolean. Simplify some variable naming while we're at it.
