gallivm/conv: enable conversion min code. (v2)

I'm not sure why this code was if (0), but if (1) for it fixes
dEQP-GLES31.functional.texture.border_clamp.range_clamp.nearest_float_color
This test expects +inf to get mapped to 255 and -inf to 0, both values
were ending up at 0.

v2: also enable in the SSE paths
