func CheckOrMountCgrpFS(mapRoot string)
CheckOrMountCgrpFS this checks if the cilium cgroup2 root mount point is mounted and if not mounts it. If mapRoot is "" it will mount the default location. It is harmless to have multiple cgroupv2 root mounts so unlike BPFFS case we simply mount at the cilium default regardless if the system has another mount created by systemd or otherwise.
