host resource should support Darwin platform

Describe the problem

Using Kitchen-Terraform, I've defined a test using the local backend that makes use of the host resource:

control 'is_host_reachable' do
  describe host(attribute('output_tfe_instance_public_ip'),
                port: 80,
                protocol: 'tcp') do
    it { should be_reachable }
  end
end

However, I get the following error when running the test on my MacBook:

Skipping profile: 'inspec-gcp' on unsupported platform: 'mac_os_x/18.6.0'

Made sure that I'm using an up-to-date version of inspec (in my Gemfile.lock):

inspec (4.6.9)

Looking at host.rb I can see that support for Darwin/MacOS was added (see inspec/inspec#1608): https://github.com/inspec/inspec/blob/490824e6ce088b59b97591d1ebcff5744b3fd539/lib/inspec/resources/host.rb#L66-L67

But doesn't seem that the appropriate platform support was defined (see inspec/inspec#2674): https://github.com/inspec/inspec/blob/490824e6ce088b59b97591d1ebcff5744b3fd539/lib/inspec/resources/host.rb#L30-L31

Possible Solution

Not sure if all it takes is to add the following?

supports platform: "darwin"

Invalid - should not have been moved from InSpec.
