Summary:This PR is to solve app build issue when node_modules is a symlink by providing an environmental variable to override the current *smart* guessing of app root path.
I met this issue when I tried to setup a shared incremental node_modules directory to speed our react-native app build speed in CI. But the build crashed in step 'bundleReleaseJsAndAssets' with error messages like:
> :app:bundleReleaseJsAndAssets
> bundle: Created ReactPackager
> uncaught error Error: NotFoundError: Cannot find entry file index.android.js in any of the roots:["/home/jenkins/shared_data"]
The build is fixed by applying this patch and adding 'export react_native_app_root=${WORKSPACE}' before './gradlew assembleRelease' in build script.
**Test plan**
1. react-native init demo # init a demo app from scratch
2. cd demo/android && ./gradlew assembleRelease # build works fine
3. mkdir ~/shared_data && mv ../node_modules ~/shared_data && cd .. && ln -s ~/shared_data/node_modules . # create symlink for node_modules in shared d
