[COOK-1099] - add a test case to show this works

This is not the recommended way to do this - we recommend a separate
recipe to install a Ruby to run the application/passenger, and adjust
this cookbook's attributes accordingly. However, this works for
testing, see .kitchen.yml `version-override` suite. It only tests
Ubuntu 12.04, as the source recipe tests other platforms and works.
