podman umount: error out if called with no args
Inspired by #2684, I wrote a CI test to look for other such instances in which a command is invoked without a required argument. 'podman umount' seems to be the only one, and solution is simple: checkAllAndLatest() already does the check for us. Resolve a few other problems uncovered by testing: podman mount: indicate that CONTAINER arg is optional podman pod stats: ditto podman generate kube: remove check for -l (latest) flag, it isn't actually implemented.
