feat: exclude node_modules from being copied to working dir (#60)

Closes #51 

As mentioned in #51 by @ChrisProlls in his [commit](https://github.com/dherges/ng-packagr/issues/51#issuecomment-307148324), we're unable to specify a source folder apart from the package.json file. So we have to exclude the node_modules folder and the typings from the template glob.
