What type of PR is this?
/kind cleanup

What this PR does / why we need it:
CI: Use the debug stdout callback instead of manual debug

This display in a readable (by humans) way the result of most tasks, and
should be way more readable that what we have now, which is frequently a
bunch of unreadable json.

+ some small fixes

This is on top of #11792 so the other one should be merged first
/hold

Does this PR introduce a user-facing change?:

NONE

This is a followup to 2ba28a3 (Revert "Wait for available API token in
a new namespace (kubernetes-sigs#7045)", 2024-10-25).

While checking for the serviceaccount token is not effective, there is
still a race when creating a Pod directly, because the ServiceAccount
itself might not be created yet.
More details at kubernetes/kubernetes#66689.

This cause very frequent flakes in our CI with spurious failures.

Use a Deployment instead ; it will takes cares of creating the Pods and
retrying ; it also let us use kubectl rollout status instead of manually
checking for the pods.
There is no pods with hostNetwork deployed in this test, and therefore
the tasks are skipped / empty output (checked in CI).

We don't test Flatcar at all in CI, thus remove special handling for it.

I think the removal of the Flatcar test case is acceptable, although it's somewhat regrettable. It would be great if we could add the Flatcar test case in the future.

Yeah I don't mind adding a test ; but in the meantime, we should not adjust for things we don't actually test.
This isn't hard to revert later if needed.

/lgtm

It's worth mentioning that I am also a fan of the yaml stdout callback plugin which is usually quite human readable, but perhaps debug makes more sense for CI.
