llvmpipe: enable PIPE_CAP_QUERY_SO_OVERFLOW

The driver supported this since way before the GL spec for it existed.
Just need to support both the per-stream and for all streams variants
(which are identical due to only supporting 1 stream).
Passes piglit arb_transform_feedback_overflow_query-basic.
