The file resource's `#content` method will return nil if the file cannot be read for permissions issues. If you try to run a profile that uses the `xinetd` resource without sudo privileges, InSpec would try to call `#empty` on nil. This change fixes this issue by checking for nil before checking for emptiness. Signed-off-by: Adam Leff <adam@leff.co>
