broadcom/vc5: Emit proper flatshading code for glShadeModel(GL_FLAT).
In updating the simulator, behavior changed slightly so that our old code
wasn't getting glxgears's flatshading interpolated right. Emit flat
shading code just like we would for a normal flat-shaded varying, by
passing a flag in the shader key for glShadeModel(GL_FLAT) state and
customizing the color inputs based on that.
