iOS: Fix compiling using the iOS 7 SDK, partially broken since MoltenVK support was added. Note that apps submitted to the iOS App Store *must* use a modern iOS SDK (currently iOS 10 is probably the minimum), however the SDK used to build is separate from the minimum iOS version an app supports at runtime.
