Revert of Enable Service Workers, including the onfetch event, by default.

Revert of Enable Service Workers, including the onfetch event, by default. (patchset #1 id:1 of https://codereview.chromium.org/680473002/)

Reason for revert:
Directory restriction of ServiceWorker sope patch (https://codereview.chromium.org/672383003/) is reverted.

We should not enable ServiceWorker without this restriction for security reason.

I will revert this patch after these patches will land.
[1/3 blink] https://codereview.chromium.org/674133004/
 Update LayoutTests to be subject to the directory restrictions.
[2/3 chromium] https://codereview.chromium.org/674133004/
 Introduce the directory restriction in Chromium side.
[3/3 blink] https://codereview.chromium.org/681483004/
 Introduce the directory restriction in Blink side and update LayoutTest.
