Title: Force number of devices to 1 so as not to break the awk script.

Sorry, I missed a not-so-edge case!

The awk snippet that grabs the cpu stats assumes that iostat's only reporting on one disk, like this:

```
disk0 cpu load average
KB/t tps MB/s us sy id 1m 5m 15m
33.00 8 0.26 6 7 87 1.46 1.49 1.57
8.96 38 0.33 2 5 92 1.46 1.49 1.57
```
...and that idle cpu % will be in column 6.

If there's more than one disk, though, the cpu stats will wind up in the "wrong" column...

```
disk0 disk2 cpu load average
KB/t tps MB/s KB/t tps MB/s us sy id 1m 5m 15m
32.99 8 0.26 151.00 0 0.00 6 7 87 1.48 1.50 1.57
0.00 0 0.00 0.00 0 0.00 3 5 92 1.48 1.50 1.57
```

This change calls iostat with -n 1, which forces it to report on only one disk.
