Kureev Alexey 5cf7f040a5 Symlink support for packager
Summary:
I saw we have quite a few user requests for symlink support...

**Test plan (required)**

1. Create a symlink in `node_modules` (for instance use `npm link`)
2. Run `npm start`
3. Profit!

**Code formatting**

Look around. Match the style of the rest of the codebase. See also the simple [style guide](https://github.com/facebook/react-native/blob/master/CONTRIBUTING.md#style-guide).

For more info, see the ["Pull Requests" section of our "Contributing" guidelines](https://github.com/facebook/react-native/blob/master/CONTRIBUTING.md#pull-requests).
Closes https://github.com/facebook/react-native/pull/9009
