Drop .stubs from android.test.[base|runner|mock].stubs

The .stubs library refer to the stub library of a java_sdk_library.
Since the name of the stub library is the implementation detail of the
build system, direct use of the name should be prohibited. Actually,
clients don't need to use the stub name directly because the build
system automatically redirects <name> to <name>.stubs.

This is a partial cherry-pick for the networking tests.
