mattjmcnaughton 5539e61032 Fix reserved cgroup systemd ...

Fix an issue in which, when trying to specify the `--kube-reserved-cgroup`
(or `--system-reserved-cgroup`) with `--cgroup-driver=systemd`, we will
not properly convert the `systemd` cgroup name into the internal cgroup
name that k8s expects. Without this change, specifying
`--kube-reserved-cgroup=/test.slice --cgroup-driver=systemd` will fail,
and only `--kube-reserved-cgroup=/test --crgroup-driver=systemd` will succeed,
even if the actual cgroup existing on the host is `/test.slice`.

Additionally, add light unit testing of our process from converting to a
systemd cgroup name to kubernetes internal cgroup name.
