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.
