test/K8sServices: redeploy Cilium before fragment tracking tests

In #11602, Cilium redeployment was removed from most of the AfterAll()
steps in the tests. It could not be removed in one case in the Service
tests, because running IPv4 fragment tracking tests with the options
used to deploy Cilium in the previous test make them fail.

Deploy Cilium with a clean configuration before running the fragment
tracking tests, and remove redeployment from that AfterAll() block at
last.
