core: remember first unit failure, not last unit failure
Previously, the result value of a unit was overriden with each failure that took place, so that the result always reported the last failure that took place. With this commit this is changed, so that the first failure taking place is stored instead. This should normally not matter much as multiple failures are sufficiently uncommon. However, it improves one behaviour: if we send SIGABRT to a service due to a watchdog timeout, then this currently would be reported as "coredump" failure, rather than the "watchodg" failure it really is. Hence, in order to report information about the type of the failure, and not about the effect of it, let's change this from all unit type to store the first, not the last failure. This addresses the issue pointed out here: https://github.com/systemd/systemd/pull/3818#discussion_r73433520
