Title: Print a useful tip about sourcing env-setup if ansible.utils can not be found

Helpful hit to avoid issues like https://github.com/ansible/ansible/issues/5105

Before
```
Traceback (most recent call last):
File "ansible/hacking/test-module", line 36, in
import ansible.utils as utils
ImportError: No module named ansible.utils
```

After
```
Can not find 'ansible.utils', as per CONTRIBUTING.md, you need to do:
source ./hacking/env-setup
```
