Fix link-type check warnings

app-helpers-*-interfaces and dpad-util modules are added with
LOCAL_SDK_VERSION so that they can be used by other apps or libs having
LOCAL_SDK_VERSION.

android.test.runner and android.test.base are replaced with
android.test.runner.stubs and android.test.base.stubs which are stub
libraries of the shared libs.

Dependency to permission-utils-lib is dropped since no one is realling
using the library. Even worse, the library is using framework internal
APIs (for granting runtime permissions) and thus it is built without
LOCAL_SDK_VERSION, which in turn makes it impossible to build other
modules using the lib with LOCAL_SDK_VERSION.
