tests: Remove tracing test cases from KafkaPolicies
tests: Remove tracing test cases from KafkaPolicies

Because of the random scheduling of the pods under test, the
tracing commands may run on a different node from all the pods,
where Cilium may be out of date re: imported policies and
identities, resulting in tracing failures.
This made those tests unreliable.
