Fix non-debug standalone version of polymer-resin.

JSCompiler was not seeing the export symbol calls because they were
in a MOE:insert comment when JSCompiler ran.

That resulted in an open-source polymer-resin/standalone/polymer-resin.js
that consisted solely of a function wrapper around a copyright header.

That was stupid of me.

Changed polymer-resin.js to use a goog.define instead.
Tested:
Ran package tests and visually checked the generated JS.
