Our timer won't be triggered automatically on initial boot if the
current date is to near on the next scheduled run, and while it would
be nicer to create a dedicated service with a ConditionFirstBoot, this
seems a bit overkill for now, so just check if the pveam log exists,
and if not trigger a daily update, which will generate such a log.
Do so after pveproxy started in ExecStartPost and allow this to fail
by prefixing the call with -.
