Fix runc ps issue

After #1009, we don't always set `cgroup.Paths`, so
`getCgroupPath()` will return wrong cgroup path because
it'll take current process's cgroup as the parent, which
would be wrong when we try to find the cgroup path in
`runc ps` and `runc kill`.

Fix it by using `m.GetPath()` to get the true cgroup
paths.
