kernel - Reduce priority range from dynamic priority
* Reduce the priority range that the estcpu mechanism can move a process
over. The general effect is that a nice +20 process will now get much
less cpu than it used to verses a nice +0 process.
* In addition, due to the change, a nice +20 process will not get any cpu
at all verses a nice -12 or lower process. Before a nice +20 process
would always still get a little cpu verses a nice -20 process, but that
will no longer be the case.
