In node_modules, follow symlinks until the "real path" is found.

Test Plan:

None yet.

Mind fixing tests and adding one test case to cover this scenario?

When I can find time, but it'll be a while.

@aleclarson this looks good but I'd like to add more an extra test. Added a check for visited array size, which fixes both unit tests and my test setup.

Btw while testing this I've finally found a way for us to run linked start command:

# when @react-native-community/cli is linked
REACT_NATIVE_APP_ROOT=/path/to/react-native-cli yarn react-native start
# or when it's not
REACT_NATIVE_APP_ROOT=/path/to/react-native-cli node /path/to/react-native-cli/packages/cli/build start
