Update test data for fonttools splitCubicAtT fix

fonttools improved splitCubicAtT to ensure the first segment starts
exactly at pt1 and the last segment ends exactly at pt4, eliminating
floating point drift (e.g. 250.00000000000003 -> 250.0).

Regenerated expected output for Q and QTail_reversed glyphs across
all boolean operation layers (union, difference, intersection, xor).
