gallivm: only use lp_build_conv 4x4f -> 1x16 ub fastpath with sse2

This is relying on lp_build_pack2 using the sse2 pack intrinsics which
handle clamping.
(Alternatively could have make it use lp_build_packs2 but it might
not even produce more efficient code than not using the fastpath
in the first place.)
