Don't wait for the final deletion of pod

The final deletion of the pod depends on kubelet and other components operating correctly. The purpose of this e2e test is verifying the clientset can handle deleteOptions correctly, so waiting for the deletionTimestamp and deletionGraceperiod get set is good enough.

In the long run, we should move this set of e2e tests to integration tests.

Fix #42724 #42646
