This replaces the internally used hard coded Node.js core module list with the actual internal existent modules. That way all modules are automatically picked up instead of having to update the list manually. This currently only applies to the REPL and to the Node.js `eval` functionality (User passed `-e` or `--eval` arguments to Node without `-i` or `--interactive`).
