Google VR causes app to close on splash screen for shipping builds on iOS

[NickW] This is because the app needs permissions for the camera in the plist when deploying on iOS.

------------------

Google VR appears to crash on a shipping build when installing onto an iOS device

1. Create a new C++ project on a mac
2. Enable Google VR plugin
3. Restart project
4. Open Xcode
5. Build project
6. Set build configuration to Shipping
7. Package for iOS
8. Install on to device (iPhone7+ used for original test)
9. Open app on device
10. Notice that the app closes immediately on the opening slash screen

Expected: The app would open and enter in to VR mode
Result: App closes as soon as the default splash screen shows up
