Add ow2-asm dependencies for GWT plugins

In GWT 2.7 asm isn't shipped any more in gwt-dev JAR. In Ib8f9ed0c7 asm
dependency was added as transitive dependency to gwt_binary() rule
invocation. Unfortunately the gerrit plugin code path was missed, thus
the plugins that make use of GWT module cannot be compiled any more.

This bug wasn't noticed, because no core plugins make use of GWT
modules.
