Summary:
the Server DVD now just has 'Fedora Server' and 'Custom
Operating System' environments. Custom is basically minimal.
So we can use the DVD for 'universal' testing again, these
needles match the anaconda_minimal tags.
Test Plan:
Run the 'universal' tests on a DVD ISO with these
needles added, test that they work OK and use the 'Custom' env.
