kernel - do not wire user pages in sysctl
* sysctl processes have not assumed that user pages would be wired
for a long time.
* This also prevents sysctl from causing VM faults on the user memory
after returning due to wiring changes.
For example 'vmstat 1' no longer produces faults in the flt column
generated by vmstat itself on every iteration.
