UPSTREAM: 96571: Use the busybox shim image constant

Instead of hardcoding fedora:latest, use one of our e2e images as
source inside the created pods. This will allow users who test with
this data outside of integration environments to reference a real
image and avoid spurious errors. Offline clusters no longer try
to create a pod pulling from DockerHub.
