GL_OES_standard_derivatives is always advertised in the extension string but is only supported with PS version 2.x and later #392

The dsx and dsy PS instructions were added in ps_2_x:

This is the cause of Chromium bug http://crbug.com/122145 which reproduces on 
GPUs that support ps2.0 but not ps2.x.

I have a patch for this here: https://codereview.appspot.com/7027051/
