Add "Restart=always" to the systemd unit file

The health-monitor daemon is not one-shot and should restart when it
gets terminated, so adding "Restart=always" to the systemd unit file.

Tested:
Before this change:
root@bmc:~# pidof health-monitor
310
root@bmc:~# kill -9 310
root@bmc:~# pidof health-monitor
root@bmc:~# # (Does not restart)

After this change:
root@bmc:~# pidof health-monitor
12839
root@bmc:~# kill -9 12839
root@bmc:~# pidof health-monitor
12904
