Only bundle the src/display/node_utils.js file in GENERIC-builds

Browse Source 
This first of all simplifies the file, since we no longer need dummy-classes and can instead *directly* define the actual classes.
Furthermore, and more importantly, this means that we no longer need to bundle this code in e.g. MOZCENTRAL-builds which reduces the size of *built* `pdf.js` file slightly.
