Add smoke test for jni library

Since the Framework net test require jni library
libnetworkstatsfactorytestjni, but the test fails to load that library
unless *all* the dependencies of that library are explicitly listed in
jni_libs, whenever any of the dependencies changes the framework net
test will start failing and it might not be catched since the change
might not related to frameworks/base. And this smoke test is aimed to
spot those native library changes and it should be stable enough to put
in global presubmit.
