Include the primary domain in the Content-Security-Policy explicitly if there's no CDN

Browse source 
Summary:
Ref T4340. If you don't configure a CDN and visit a custom site (like a Phame blog site, or a CORGI sandbox internally) we serve resources from the main site. This violates the Content-Security-Policy.

When there's no CDN, include the primary domain in the CSP explicitly.

Test Plan: Loaded `local.www.phacility.com`, got resources.
