ci: Add label selector to pod listing

[stevenhorsman]

We only want to run kubernetes_delete_ssh_demo_pod_if_exists if the ssh-demo pod exists, so lets select for this pod using the label to try and ensure we don't pick up other pods.

@wainersm - can you take a look at this and see if it helps the problem please? Unfortunately due to the problems with https://github.com/kata-containers/kata-containers/issues/5044 and https://github.com/kata-containers/tests/commit/97664005126c69b424eab18b695287bf15a53773 I can't reliably test it at the moment.
