Add an integration test to verify ndk libs are not included
android apps that target an sdk should not embed an ndk lib even if
one of its jni libraries has a transiive depdencny on it.
Add an integration test that asserts this behavior for `b` built apps.
Bug: 301295448
Test: b run //build/bazel/examples/android_app/java/com/app:no_ndk_libs_in_android_app --config=android
