ceph-infra: update handler with daemon variable

Both ntp and chrony daemon use variable for the service name because it
could be different depending on the GNU/Linux distribution.
This has been update in 9d88d3199 for chrony but only for the start part
not for the handler.
The commit fixes this for both ntp and chrony.
