Ian Dowse 0eb6ce3169 Move the code that computes the system load average from vm_meter.c
to kern_synch.c in preparation for adding some jitter to the
inter-sample time.

Note that the "vm.loadavg" sysctl still lives in vm_meter.c which
isn't the right place, but it is appropriate for the current (bad)
name of that sysctl.
