Raise difference tolerance for video_detector.js
The WebRTC PyAuto tests have flakiness in the
webrtc_call.WebrtcCallTest.testMediaStreamTrackEnable
test on Windows due to the fact that the disabled mediastream
track still produces somewhat changing pixel data for the video
tag that is captured on the canvas tag during the "is video
moving"-detection.
Raising the tolerance a bit solves this problem for now. We want to
minimize the work put into this test as it's going away soon.
TEST=running locally on the Windows 7 tester.
