Remove the R/Manifest classes when building the static Java library

Bug: 5448433

Instead of deferring the removal to building the app.
In that case any R/Manifest classes in any static Java libraries will be
deleted, no matter if they are generated from Android resource, or just
source R.java/Manifest.java in the source tree by accident.
