It can be useful to load dependencies as part of the loader hook definition file. This fixes a bug where import x from 'x' would always return x as undefined if the import was made in a loader hooks definition module.

A parallel change to the CJS loading injection process which happens in https://github.com/nodejs/node/blob/master/lib/module.js#L521 meant that the CJS module wasn't being injected into the correct loader instance, which is corrected here with a test.

Ok, looks like all are passing except for one failure which seems CI-system-related.
