llvmpipe: enable PIPE_CAP_INDEP_BLEND_FUNC

The driver was saying that independend blend functions was not supported,
but it really was.  The driver was using the per-target independend blend
factors but the state tracker was only setting the 0th one (per the
Gallium spec).

Fixes a piglit fbo-drawbuffers2-blend regression.
