Dynamically link static libs for sdk_library created java_library

Rename java_library created inside sdk_library with the ".from-source"
suffix, and set it as static lib of the top level java_library, which
gets java_api_library instead as static lib during from-text stub build.

Test: m nothing && m nothing --build-from-text-stub
