cpuidle: governors: teo: Avoid fake intercepts produced by tick

Tick wakeups can lead to fake intercepts that may skew idle state
selection towards shallow states, so it is better to avoid counting
them as intercepts.

For this purpose, add a check causing teo_update() to only count
tick wakeups as intercepts if intercepts within the tick period
range are at least twice as frequent as any other events.
