Per our discussion, you can just use existing SetGLStrings().
your "vendor" can be gl_vendor, and your "device" can be gl_renderer.  This will
make this CL much simpler. Just make sure the vendor supplies these two values
the same as they supply GL_VENDOR and GL_RENDERER in the OpenGL driver.
(Otherwise when you launch GPU process and create a context, these two fields
may be overwritten with a different value, and cause the blacklisting to change.
