mesa: Fix fragment.color (no index) writes with OPTION ARB_draw_buffers.
Fixes a bug in Trine where fragment.color would write
FRAG_RESULT_COLOR (which is interpreted by drivers as being the "write
this to all color buffers" option) instead of FRAG_RESULT_DATA0 (just
the first target).
Fixes piglit ATI_draw_buffers/arbfp-no-index.
