java: add one-off build logic for frameworks/base

framework.jar needs to compile against R.java and Manifest.java from
framework-res.apk.  Rather than complicating the Blueprints properties
with values that will only be used once, add one-off logic to
collectDeps to extract the rJarSpec out of the framework-res module.
