Increase the maximum of UMA metric Event.Latency.RendererImpl.GestureScrollUpdate

On some pages where there is TouchEvent handler and main thread is
really busy, the UMA metric Event.Latency.RendererImpl.GestureScrollUpdate
can easily reach the maximum of 200ms. Lets increase the maximum
to 1000ms to have a better reading of the distribution.

BUG=326594
Test=Test on www.rbyers.net/janky-touch-scroll.html and see that the
     distribution of  Event.Latency.RendererImpl.GestureScrollUpdate
     makes more sense.

Add --disable-avfoundation to the command line for browser_tests.

AVfoundation is present in Mac OS X >= 10.7 (Lion).

Browser_tests in Mac uses ManyCam as a camera device. Manycam
does not work with AVFoundation, so temporarily we force QTKit
for the tests to run. If ManyCam starts being correctly 
supported in Mac with AVFoundation, this patch can be 
reverted (see bug).

(FI, Longer term we'd like to move most of the tests to 
FileVCD, and leave a very reduced amount of physical devices 
to test real hardware/OS interactions.)
