Link libraries with unstable ABIs statically into libnativebridge-tests.

It incorrectly used art_test_internal_library_defaults, which requires
setting NATIVELOADER_DEFAULT_NAMESPACE_LIBS to work.

It still links several test libraries dynamically, but that works fine
since they're pushed with the test.

Add a test config to enable pushing the test libraries. It's the same
as art-gtests-target-standalone-template.xml, except `append-bitness`
isn't passed to the file pusher, which apparently disables pushing the
whole test directory.

Test: atest libnativebridge-tests
Test: readelf -d out/target/product/vsoc_x86_64/testcases/libnativebridge-tests/x86_64/libnativebridge-tests64
  -> Check that no unstable libraries like libc++.so are linked
  dynamically.
