r300: Fix fogcoord rewriting
We only care about the actual fogcoord itself now, reducing the rewriting done for the vertex program. The rewriting of source operand swizzles in the fragment program takes care that fogcoord.yzw = 001. This should fix fogcoord rewriting entirely, which had been horribly broken in the face of dot-product instructions, and just broken (though not horribly so) in the face of almost every other instruction (the W component would be incorrect for most arithmetic instructions).
