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.
