svga: fix vgpu9 sprite coordinate bug

Setting GL_POINT_SPRITE_COORD_ORIGIN to GL_LOWER_LEFT did not work for
vgpu9.  We can use the rasterizer sprite_coord_enable bitfield as-is.
We need to index into it using the TGSI semantic index, not the
register index.

This fixes the Piglit fbo-gl_pointcoord and glsl-fs-pointcoord tests.

Testing done: Piglit, Mesa sprite demos
