Generation logic of deps.js is outdated.

[KOH922]

The current plovr RAW mode does not support the module_flag parameter of goog.addDependency(). https://github.com/bolinfest/plovr/blob/952e2b151713aaecf570c2e24349465a056e5a9f/src/org/plovr/Manifest.java#L485-L493

Closure-Library now takes module_flag as the 4th argument and can now specify module,lang.

If module does not contain goog, it will not correctly parse goog.module(...) and an error will result. https://github.com/google/closure-library/wiki/ES6-modules-and-Closure-Library#the-debug-loader-and-es6-modules
