This fixes an issue where Stats.GetSelf() would fail when run inside a container while using a hostfs path, as the PID returned by os.Getpid() would not be valid outside the container runtime.
This changes the logic, so if we have a hostfs set, GetSelf will fetch the pid from /hostf/proc/self.
Why is it important?
This is a bug.
