test/e2e_node: prepull images with CRI

Part of https://github.com/kubernetes/kubernetes/issues/40739

- This PR builds on top of #40525 (and contains one commit from #40525)
- The second commit contains a tiny change in the `Makefile`.
- Third commit is a patch to be able to prepull images using the CRI (as opposed to run `docker` to pull images which doesn't make sense if you're using CRI most of the times)

Marked WIP till #40525 makes its way into master
