Allow dns e2e test case for ExternalName to run on aws

**What this PR does / why we need it**:
#52840 uses allocated clusterIP instead of hard-coded one. So we don't need to care about the clusterIP range of the CI job config. Let it run on pull-kubernetes-e2e-kops-aws

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #47224
