Revert "Use subprocess2 for downloading tools."

This reverts commit 4d39dc392294807d84eefb1c7414f807d9b4855b.

Reason for revert: To benefit from the other fix in crbug.com/773671. Will reland once DEPS rolling is unblocked.

Original change's description:
> Use subprocess2 for downloading tools.
> 
> Change to use exactly the same approach as when gclient hooks
> are executing [1]. It should be safe since it's using the DEPS-pinned
> depot_tools in third_party. Hopefully this solves the race condition
> problems we've been seeing in crbug.com/773671

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development

See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.
