[Tether07] Clean up build rule for libtetheroffloadjni

- Statically include android.hardware.tetheroffload.config@1.0,
  libcutils and their dependency library.
- Use shared-lib if there is NDK or NDK-compliant version
- Remove android.hardware.tetheroffload.control-V1.0-java from
  service.core because it is already statically built in tethering apk
