Disable GL_EXT_texture_rg with GLES 2.0 on Mesa drivers prior version 11.1

Because it wrongly claims supporting GL_EXT_texture_rg.
The bug in Mesa has been fixed in 11.1:
https://bugs.freedesktop.org/show_bug.cgi?id=93126

Video playback rendering is done differently in Chromium
depending if this extension is supported or not. If it
uses the extension whereas the driver actually does not
support it, this leads to green video frames.

BUG=545904

TEST= --use-gl=egl on Mesa drivers
