mesa: fix num_draw_buffers==0 in fixed-function fragment program generation
This fixes a problem when glDrawBuffers(GL_NONE). The fragment program
was writing to color output[0] but OutputsWritten was 0. That led to a
failed assertion in the Mesa->TGSI translation code.
NOTE: This is a candidate for the 7.9 and 7.10 branches.
