glsl: Don't remove XFB-only varyings.
Consider the case of linking a program with both a vertex and fragment
shader. The VS may compute output varyings that are intended for
transform feedback, and not read by the fragment shader.
In this case, var->data.is_unmatched_generic_inout will be true,
but we still cannot eliminate the varyings. We need to also check
!var->data.is_xfb_only.
Fixes failures in ES31-CTS.gpu_shader5.fma_precision_*, which happen
to use transform feedback in a way we apparently hadn't seen before.
