test(nat): Add debug logs for vpc-routing, flow-lookup in NAT test

Additional logs turned out to be helpful to understand what was going on
during the test. Let's keep them on in order to obtain more information
if this test ever fails again.

Given that we need to remove the "#[traced_test]" annotation, we re-add
logs for target "stateful-nat" manually.
