Drop Virtual webcam check script as moved into buildbot scripts.

Having this script being located in the WebRTC repo doesn't make sense
since it has no connection to the source code.
Updating this script should apply to all build configurations and since
this script will be used for Chromium builders, we'll end up with having
to wait for a new WebRTC revision to be rolled in DEPS before it's updated.

-"""Checks if a virtual webcam is running and starts it if not.

-Returns a non-zero return code if the webcam could not be started.

-Prerequisites:
-* Python must have the psutil package installed.
-* Windows: a scheduled task named 'ManyCam' must exist and be configured to
-  launch ManyCam preconfigured to auto-play the test clip.
-* Mac: ManyCam must be installed in the default location and be preconfigured
-  to auto-play the test clip.
-* Linux: The v4l2loopback must be loaded to the kernel already (with the
-  devices=2 argument) and the v4l2_file_player application must be compiled and
-  put in the location specified below.
