Subject: [PATCH] journald: fix accuracy of watchdog timer event

Adding 3/4th of the watchdog frequency as accuracy on top of 1/2 of the
watchdog frequency means we might end up at 5/4th of the frequency which
means we might miss the message from time to time.

Maybe fixes #1804

(cherry picked from commit 4de2402b603ea2f518f451d06f09e15aeae54fab)
