Another last step of many to porting blink CSP tests to WPT

This has been a long time overdue but there are too many things currently
blocking on this so it's time to look at the blink-contrib folders.

Goals are to:
- get rid of checkreoport in tests that don't actually require it

This should unblock `checkreport` changes that break the upstream
integration.
