tests: Fix weird error on centos-9

[rata]

centos-9 unit test sometimes fails with:

            === RUN   TestPodSkipDevicesUpdate
                systemd_test.go:114: container stderr not empty: basename: missing operand
                    Try 'basename --help' for more information.
            --- FAIL: TestPodSkipDevicesUpdate (0.11s)

I'm not sure why the container output is an error in basename. It seems
likely that the bashrc in that distro is kind of broken. Let's just run
a sleep command and forget about bash.

Fixes: #3742

I think this should do the trick (if sleep command there has the infinity option, unsure if all distros have it). But let's see... I'm pushing this commit to other open PRs I have, to run it more times

Pushing to foce it to run again

Well, that seems fixed but there is yet another issue, now in integration tests:

Opened another issue for that one :(

All green now!
