fix undefined_arch error in Xcode 10 beta (#19841)

Summary:
Fixes #19774

I spotted that in  Xcode 10 beta `CURRENT_ARCH` is set to string `undefined_arch`.  This PR will add fallback based on platform name (simulators are `x86_64` and everything since iPhone 5s is `arm64`).
Closes https://github.com/facebook/react-native/pull/19841
