e2e: adapt play kube test on remote rootless

[sstosh]

Use podmanTest.PodmanBinary because podman-remote unshare
cannot be used.

Does this PR introduce a user-facing change?

None

[sstosh]

The CI/CI system currently doesn't run on remote rootless.
Therefore, this test wasn't failed.

However, it still fails even if applying this commit,
because podman-remote --userns=auto doesn't work.

Maybe related to #16795

LGTM.

Sorry for tardy review; it took me a while to convince myself that this test is meaningful under remote.
