Build Cache for React Native v0.17.2

Changelog

What’s Changed

  • Bumps the CLI to v3.9.2, which fixes React Native iOS builds installing the app from the wrong DerivedData.
  • The wrapper relocates DerivedData but only told xcodebuild about it on build actions, so -showBuildSettings still answered with the default location. @react-native-community/cli locates the built .app from that answer, so installApp walked to a path the build never wrote and failed with lstat ... .app: No such file or directory.
  • The build itself and the cache were fine — only the install step failed, which broke iOS e2e suites on projects that activate the cache and then install the app.
