ceph-daemon: do not relabel system directories

These are shared system directories and should not be relabled for use by
ceph containers.  (Also, trying to relabel /dev prevents the container
from starting, e.g.

# /bin/podman run -it --net=host  --privileged    -v /dev:/dev:z    --entrypoint bash centos
Error: relabel failed "/dev": SELinux relabeling of /dev is not allowed

)
