Stop autolinking iOS-only Node-API modules when running pod install for react-native-macos #272

Here, I have an iOS + macOS project that installs both @nativescript/ios-node-api and @nativescript/macos-node-api.

For one thing, there's no need to link the iOS package when I'm running a pod install for my macOS app, and yet it still does so:

For another thing, I seem to be getting a relevant build failure. I wonder if my macOS app is being forced to link against the iOS framework or something?

For now, I'll work round it by uninstalling @nativescript/ios-node-api from this demo repo. Just trying to see some signs of life.
