[e2e] Bump up pod deletion time for source pod IP test

From #44225.

Source pod IP e2e test is pretty flaky lately, and most of the failures seem to be timeout waiting for pod "kube-proxy-mode-detector" to disappear. Didn't found any other thing suspicious.

This PR bumps pod deletion timeout to DefaultPodDeletionTimeout, which is 3 minutes. Hopefully it will mitigate the flakes.
