goog.module in RAW mode

[KOH922]

The current plovr RAW mode inserts all dependency files with <script> element via document.write(). However, a Module *** has been loaded incorrectly error occurs at goog.module() and the load fails. https://github.com/google/closure-library/blob/8da4a938c86e313d37d64f635e364dfef5882e9b/closure/goog/base.js#L431 goog.module() can be executed only when debug loader is called in goog.require().
