watchdog: add support for starting/stopping kernel watchdog
Extend the ubus watchdog cmd with the parameter magicclose; when set and
in case the stopped parameter is enabled the kernel watchdog will be stopped
by first sending the magic character 'V' followed by a close of the watchdog
fd. In case stopped is set to disabled the watchdog fd will be created again.
