ci: wait longer for pod label to be deleted
ci: wait longer for pod label to be deleted

I've seen cases were the CI needs a few more seconds to delete and
object store. When logging in the runner, the object store is gone and
the timing matches too with the runner's logs (comparing with the
operator's logs).
