Speed up the AIX hostname specfaster_spec

Mock out #resolve_fqdn like we do in all the other plugins to avoid actually checking the fqdn on the host running the specs.

This was our #2 slowest spec:

```
  Ohai::System AIX hostname plugin sets the machinename
    0.85031 seconds ./spec/unit/plugins/aix/hostname_spec.rb:30
```
