Disable clockcheck and kernel leap with ntpshm servo. 

Always disable the clock sanity check when the ntpshm servo is used,
because it doesn't know when or how is the clock adjusted. Disable also
the kernel leap option as the process controlling the clock is
responsible for setting the kernel flag.
