Otherwise encounter this failure in the CI on FreeBSD:
```
salt.exceptions.SaltRenderError: Jinja variable 'dict object' has no attribute 'oscodename'
[CRITICAL] Pillar render error: Rendering SLS 'openssh' failed. Please see master log for details.
```
The debug output of test jobs don't show the use of TOFS as it should
and the pillar.example show that `tofs` is under `mine_functions`
instead of `openssh`.
* pillar.example: move `tofs` under `openssh`.
* test/salt/pillar/default.sls: ditoo.
* Close#165
* Move existing `.kitchen.yml` => `kitchen.vagrant.yml`
* Semi-automated using https://github.com/myii/ssf-formula/pull/30
* Fix errors shown below:
```bash
openssh-formula$ yamllint -s .
