fix logic error + little refactor
Fix: get cptime of n-th cpu when `percpu` instead of the average.

While there, rearrange the last if statement to make the code a bit
more homogeneous.

Lomanic 974d52d412 [load][darwin] Remove calls to sysctl binary in load/load_darwin.go #639
Again, a simple benchmark:

Lomanics-iMac:~ lomanic$ time ./load_avg.old ; time ./load_avg
{load1:0.89,load5:0.99,load15:1.01} <nil>

real    0m0.019s
user    0m0.008s
sys     0m0.013s
{load1:0.8876953125,load5:0.98828125,load15:1.0146484375} <nil>

real    0m0.011s
user    0m0.004s
sys     0m0.006s

This is faster and yields more precise results.

This gives us the value of actual online CPUs (as opposed to the
found ones which may not be able active).
