kboot: Add host_exit and use it to implement exit()
Clients of libsa are expected to implement exit(). The current exit just loops forever. It is better to really exit: when running as init that will reboot the system. When not running as init, other programs can recover (not that we support running as init, but when we do in the future, this is still the rigtht thing). Sponsored by: Netflix
