Patch for kern_racct.c that permits CPU limiting beyond 100%

This is the patch I've been using on 10.1-STABLE #11 r277139M. It uses a more
reasonable CPU limit which is 100% * MAXCPU. It would be nice to get this
rolled into the distribution; I can't imagine multi-core CPU limits have worked
for anyone in 10/10.1.

For anyone who wants to try this, apply as follows before rebuilding the
kernel:

 patch /usr/src/sys/kern/kern_racct.c < kern_racct.c.patch
