We force the hostname in `kitchen` so the `_mapdata` files can be
static.

The use of `eq` instead of `include` premits to have a nice diff after
the `expected/got` oneliners.

We store validated `map.jinja` dump under the profile `files`
directory to access them with `inspec.profile.file('filename')` to
validate the content of the generated mapdata file.

The YAML files contain a value specific to each minion, its hostname,
so we use string format to expand `%{hostname}`.

The `default` inspec profile need to depends on `share` to access the
`system` and `salt_minion` libraries.

For Arch, Inspec define `platform[:family]` as `linux` and
`platform[:name]` as `arch`.

* test/integration/default/controls/services_spec.rb: favor modifier
  if usage when having a single-line body.

* test/integration/default/controls/services_spec.rb: ditoo.

* Refactor `package_name` using `case` like other formulas

* ci(kitchen): use `openssh.config` as `state_top`
* Semi-automated using https://github.com/myii/ssf-formula/pull/33
* test(pillar): remove deprecated option and disabled method
* https://travis-ci.org/myii/openssh-formula/jobs/585340845#L1811-L1813:
* test(pillar): use same SSH options as used by Travis
* Using existing options locks out after `kitchen converge` (before `verify`)
* https://travis-ci.org/myii/openssh-formula/jobs/585356835#L2957-L2965:
