Change podman log-driver from journald to k8s-file

* When podman runs the Kubelet container, logging to journald means
log lines are duplicated in the journal. journalctl -u kubelet shows
Kubelet's logs and the same log messages from podman. Using k8s-file
driver alleviates this problem
* Reduce Kubelet log volume by half
