[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

Bug: 143195885
Test: -build, flash, boot

+# If you don't need to do a full clean build but would like to touch
+# a file or delete some intermediate files, add a clean step to the end
+# of the list.  These steps will only be run once, if they haven't been
+# run before.

+# E.g.:
+#     $(call add-clean-step, touch -c external/sqlite/sqlite3.h)
+#     $(call add-clean-step, rm -rf $(PRODUCT_OUT)/obj/STATIC_LIBRARIES/libz_intermediates)
+#
+# Always use "touch -c" and "rm -f" or "rm -rf" to gracefully deal with
+# files that are missing or have been moved.
+#
+# Use $(PRODUCT_OUT) to get to the "out/target/product/blah/" directory.
+# Use $(OUT_DIR) to refer to the "out" directory.
+#
+# If you need to re-do something that's already mentioned, just copy

+# made today requires touching the same file, just copy the old
+# touch step and add it to the end of the list.
