sched/walt: Increase the number of history samples

Browse Source 
The number history samples should be raised to a higher value so that an
active history of 100ms is considered in accounting task demand. Raise
the history size from 5 to 8 given the default windows size is 8ms. This
will capture 64ms of history for 8ms windows, and 128ms of history for
16ms windows, granting a compromise to prevent further code bloat.
