service: make move to sub-cgroup non fatal

if we are running in a container in the root cgroup, Podman tries to move itself to a sub-cgroup. This could be a problem in a setup where the cgroups are not writeable, so just log a debug message and continue, since anyway it is a best-effort operation.
