e2e: restore build after overlapping helper additions (#2544)

#2538 and #2537 each added a kindCluster.deletePod helper. Both changes
merged cleanly, but together they leave the e2e package with duplicate
method definitions.

Keep the version from #2538 because its resilience callers recreate pods
under the same names immediately and need deletion to finish first. The
service/DNS cleanup can use the same stronger helper.
