Subject: [PATCH] FIX #9617 - Correct find local IP address when running on iOS
 device

Summary:
React native's reload javascript option doesn't always work on iOS devices since version 0.29, as described in https://github.com/facebook/react-native/issues/9617

It only doesn't work when you have a mac on a wireless connection, because react-native-xcode.sh can't find your IP address correctly in this case and will just fallback to use the pre-bundling option on your app.

This small change in react-native-xcode.sh fixed this issue for our project and should fix this issue for all mac users that use wireless connection and that will run a debug version of the app on a real iOS device.
Closes https://github.com/facebook/react-native/pull/9964
