[Piglit] [PATCH 2/2] nv_fill_rectangle: add test

[Lyude]

This adds a basic shader test for the GL_NV_fill_rectangle extension.
The test simply draws a single prim with the polygon mode set to
GL_FILL_RECTANGLE_NV and checks that the prim was rasterized as a full
rectangle, along with checking that the rectangle only occupies the
space we gave it in it's vertex data.
