[gnome-continuous-yocto/gnomeostree-3.28-rocko: 2342/8267] watchdog: Add wd_keepalive package

[Emmanuele Bassi <ebassi src gnome org>]

    watchdog: Add wd_keepalive package
    
    This is a simplified version of the watchdog daemon. It only opens
    /dev/watchdog, and keeps writing to it often enough to keep the kernel
    from resetting, at least once per minute. Each write delays the reboot
    time another minute. After a minute of inactivity the watchdog hardware
    will cause a reset. In the case of the software watchdog the ability to
    reboot will depend on the state of the machines and interrupts.
    
    Installs wd_keepalive binary and enable initscript.
