Re-enable the non-virtual version of json-module-service-worker-test

The non-virtual version of
external/wpt/html/semantics/scripting-1/the-script-element/json-module/json-module-service-worker-test.https.tentative
fails by-design without --enable-features=JSONModules, but it's missing
the expectations file for this failure and is instead disabled in
TestExpectations.

This CR adds the expectations file so that the disable in
VirtualTestSuites can be removed, and crbug.com/967018, which is
actually the implementation bug for Synthetic Modules, can be resolved
(which should have happened a while back when we finished that feature).
