Revert of Use the desktop GL core profile on Linux when ES3 support is requested. (patchset #3 id:40001 of https://codereview.chromium.org/1052153002/)
Reason for revert:
This causes Chrome rendering to break on some Chrome OS devices, see crbug.com/473891 for details
Original issue's description:
> Use the desktop GL core profile on Linux when ES3 support is requested.
>
> Request an OpenGL 4.2 context (the minimum version Chromium's WebGL
> 2.0 prototype currently requires) on Linux when
> --enable-unsafe-es3-apis is specified on the command line.
>
> Clean up the shader translator's selection of the GLSL output format.
>
> BUG=471960
