Ensure haos-wipe service can be called only once per boot (#3924)

Browse Source 
In some cases, the wipe service may be called due to a race condition for the
second time during the boot, very likely failing because the filesystems are
already mounted. This can not be reproduced on OVA but can be fairly easy
triggered e.g. on RPi. As we want the service to be executed exactly only once,
we can do what's suggested in [1] and set the RemainAfterExit=yes. That should
ensure the unit is not ever started for the second time.
