Make cpu_est_clockrate() more accurate by disabling interrupts for the

millisecond it is calibrating.  Suggested by jhb@ and bde@.  Don't clobber
the tsc_freq with the new value since it isn't accurate enough for
timecounters and the timecounter system as a whole needs support for
changing rates before we do this.  Subtract 0.5% from our measurement
to account for overhead in DELAY.  Note that this interface is for
estimating the clockrate and needs to work well at runtime so doing a full
calibration including disabling interrupts for a second is not feasible.
