PDFViewerUpdate: Run ServiceWorkerJSTests with both flag states

These tests run the basic_test.js tests after loading the service
worker. As a result, now that basic_test.js has been adapted to run
with the flag enabled in
https://chromium-review.googlesource.com/c/chromium/src/+/2376871,
these tests pass with both flag states and just need to be
parameterized so that they are run on the bots with both.
