Fix broken cpu_sup:nprocs and others on Solaris 64-bit
The correct kstat datatype for nproc & avenrun_* is ui32, not
ulong. Under 64-bit OTP builds garbage was returned because the wrong
datatype was used.
This patch correcs the datatype. It also adds an additional check
in the test case for a slightly less insane return value.
