Fix a possible panic occurring if the cilium-health test fails and flow validation is enabled, or --print-flow is given. Indeed, that action is configured with a nil destination (as the check has no strict destination target), in turn causing the panic during flow visualization. Hence, let's switch to creating a generic action (i.e., intended for generic assertions), effectively disabling flow collection and display.
