Fix recursive header expansion falied

[MatthieuLemoine]

Use SRCROOT instead of PROJECT_DIR to fix the following error :

Argument list too long: recursive header expansion failed

Fix #1250.

Also adds React and React Native header search paths as mentioned in https://github.com/react-native-community/react-native-camera#ios step 5
