Add platform, version to spec files

This patch adds platform and version to the spec files. Without it,
every single test results in this warning:

WARNING: you must specify a 'platform' and 'version' to your ChefSpec Runner and/or Fauxhai constructor, in the future omitting these will become a hard error. A list of available platforms is available at https://github.com/customink/fauxhai/blob/master/PLATFORMS.md
