Add a flag to wdogctl(8), -x, that activates a user-mode timer that
is NOT disarmed when wdogctl closes the watchdog device. The -x mode protects against the case where the kernel kills wdogctl, sshd, and other essential userland programs (due to memory exhaustion, for example), lobotomizing a mission-critical NetBSD system and necessitating an operator visit to reboot it.
