ensure-env-cip-auditor: fix chicken-egg problem around Cloud Run endpoint

The cip-auditor Cloud Run service must exist (have a HTTPS endpoint) in
order for the ensure-env-cip-auditor.sh script to fully execute and set
up Pub/Sub subscriptions, etc. However, the Cloud Run service cannot be
deployed without first running the ensure script in order to set up the
correct APIs and such. This chicken-egg problem can be solved by
deploying a dummy image to Cloud Run if it doesn't exist yet.
