i965: Fix bug in the old FS backend's projtex() calculation.

In the old backend, we looked at any FS attribute's proj_attrib_mask bits, not
just texcoords.  Now that we have _mesa_vert_result_to_frag_attrib(), we can
fill in the other FS inputs with correct proj_attrib_mask info.

NOTE: This is a candidate for stable branches.
