ImageCapture.grabFrame()/<video>.captureStream(), use ABGR pixel format for Android

This CL corrects the code to use the pixel format: must use
ABGR instead of the incorrect ARGB, for the JS APIs
mentioned in the title and for Android platform.

BUG= 627983 

Verified on N7.2, N6.

TEST= two parts, e.g. on a N5X or N6 phone:
1) Navigate to [1], open either camera, click on
grabFrame() and verify correct colours
2) Navigate to [2], click on "Start <video> playback",
then on "Create Stream..." and then on "Play back..."
and verify correct colours.
