Disable pre-submit host unit-testing for `libnativebridge-tests`.

Test module `libnativebridge-tests` is not compatible with TradeFed
(because of its use of the `test_per_src` feature) and is meant to be
executed with the `tests/runtests.sh` script instead.

(cherry picked from commit ccf4f91f7768e8ed14a685f5bbbb0bf03e467081)

Test: Execute `m host-unit-tests` and check that the generated
      `host-unit-tests.zip` test suite does not contain any
      `libnativebridge-tests` test case.
Test: art/libnativebridge/tests/runtests.sh
