ahanriat a3706411ab Fix jest preprocessor script
Summary:
Related to #3999

There is an issue with the `preprocessor` script when using node >=5 as it uses npm 3. ~~There are (at least) two solutions, (I'm submitting the first one):~~
- ~~specify min required node version to 5.x and modify [this the preprocessor script](https://github.com/facebook/react-native/blob/0.16-stable/jestSupport/preprocessor.js#L29) to match npm 3 requirements~~
- ~~specifify node version >= 4.x and < 5.x and let the preprocessor script as it is~~

**EDIT**:
Using `require.resolve` will do the trick !
