Disable CMAA on Tegra

CMAA makes graphics_WebGLPerformance go from 2 failures to 67 failures.
These failures are triggered by GL errors:

GL ERROR :GL_INVALID_FRAMEBUFFER_OPERATION : glFramebufferTexture2D

Let's disable CMAA so we don't break WebGL on Tegra.

BUG=b:67387379,  chromium:787087 
TEST=graphics_WebGLPerformance failures return to normal on Tegra
NOTRY=true
