Kernel tests: drop the mixed arc-and-line mitre test, the rig's 485 grades it

Browse Source 
fillet_mixed_arc_and_line_joint_preserves_both_section_radii put R0.5 on the
D prism's top outline and checked 258 points of each mitre edge against the
cylinder and torus to 1e-7 in r squared, through the record's edges. The rig's
fillets/485-fillet-d-prism-top-outline-arc-and-flat builds the same prism with
the same radius and grades the removed volume to 5e-5 (a 0.12 mm3 loss shows)
and G1 on every blend seam, which is what the mitre's accuracy is for.
