Reason for revert: Breaks the bots.

Original change's description:
> Make it possible to run video_quality_loopback_test in swarming.
> 
> I made two changes to video_quality_loopback_test to make it possible
> to run it on swarming.
> 
> 1. We need to know the path to frame_analyzer when we're generating
>    the build files, and it must be already present.
>    I made frame_analyzer a resource, so it's downloaded to a known path
>    before generating the build files.
> 2. The .zip files for apprtc and golang are downloaded and isolated.
>    The script now extracts them and installs AppRTC.
> 
> Passing task:
