We use the $WATCHDOG_USEC variable for two very closely uses: as part of the sd_watchdog_enabled() protocol for implementing service watchdogs. And as part of the protocol between the service manager and systemd-shutdown across the PID 1 execve() transition during shutdown. Apparently some exitrds tools got confused by the latter use. Let's address that by setting $WATCHDOG_PID to 1, in accordance to the sd_watchdog_enabled() protocol to make clear this is only intended for PID 1 and nothing else. Replaces: #35135 (cherry picked from commit 4b20ae9a0e914e61d6bac095e5fc9664510ac03e)
