In podman we have code to move a process into a new systemd cgroup. This
code lived in the podman utils package. Because the new rootlessnetns
must call into that move this code to c/common.
Instead of dumping this again into a "util" package create a systemd
package which should have a better name. Also move the cgroup code
directly into pkg/cgroup. I am sure we can do some cleanup there in a
followup to prevent duplication.
