When targeting nodejs with no optimizations, add headers the same way as with optimizations.

This is to fix bug http://dev.clojure.org/jira/browse/CLJS-1454. The counterpart for optimized builds can be found here: https://github.com/clojure/clojurescript/blob/master/src/main/clojure/cljs/closure.clj#L1723
