Revert of Now pulling WebRTC telemetry pages from https instead of http.

Revert of Now pulling WebRTC telemetry pages from https instead of http. (patchset #2 id:20001 of https://codereview.chromium.org/1313873002/ )

Reason for revert:
Breaks http://build.chromium.org/p/chromium.perf/builders/Linux%20Perf%20%284%29.

Original issue's description:
> Now pulling WebRTC telemetry pages from https instead of http.
>
> https://codereview.chromium.org/1301653005 changed getUserMedia so it
> only works for secure origins, which led gUM to be blocked. This patch
> makes us pull our demo pages from https instead of http. Web page
> replay seems to respect https, and will play back as https, so this
> should solve the problem.
