Known failing on solidcore after the f916a8d sync; blend_fit in the entry-point guard

SMLib f916a8d's setback corner (smlib#104: three rounds of different radii, the curvature
rounds' G2 corner, too-short setbacks refused naming the least) is solidcore#2310, not ported
yet: five tests that now want it fail on solidcore. Main's three tests that assume truck fail
here as on SMLib. blend_fit asks no kernel on solidcore (it names no size there yet).
