ci: add delay on podvm smoke-test

1s delay between claiming an IP address and launching kata-agent is not
enough in some cases, resulting in a flaky test.

Changing the delay before attempting to connect to the agent to 5s seems
to resolve the issue. Running the test in a loop with 25+ launches didn't
produce a failure, while doing the same with the original 1s delay, will
result in "connection refused" failure after a couple of runs.
