Fix serious launch issue preventing DIND shutdown when dockerd not running

Due to a couple of missing spaces, launch-time checks that dockerd is up-and-running failed to perform correctly, meaning that DIND could launch and begin polling for container launches without having properly configured iptables and other things needing configuration.

This could cause a serious outage if dockerd is restarted on a node.

Upgrade to v3.2.0 highly recommended.
