CSP: Verify that report-uri accepts scheme-relative URIs.
Just adding a layout test; the code already works as expected when 'report-uri'
is populated with a URI like ‘//example.com/violation-report-endpoint'.
This test is being added as part of Bug 154288.
Marking as duplicate because this patch was included as part of the recent CSP 2.0 work. See Bug 154288 for more details.
