Move ServiceWorker public headers to public/*/modules/serviceworker (1.5/3)

The change was supposed to be made in three-sided patch:
[1] (blink) https://codereview.chromium.org/1262943002/
[2] (chromium) https://codereview.chromium.org/1254023006/
[3] (blink) https://codereview.chromium.org/1262603004/

But the change [1] needed to duplicate one header file (rather than
having a forwarding include) and a changes made between [1] and [2]
wasn't copied to the dup'ed file.

This change's making the same change made in the old location
to the new location.

I also added a FIXME comment so that we could keep the files in sync
until we land [2].
