localize mathutils dependency in tests #3895

replaced shapebuilder with general ifcopenshell code in `test_add_boolean` (the only place besides `test_shape_builder` where it was used), that way mathutils dependency in tests is localized only to `test_shape_builder.py`.

added test-safe option to makefile, so github workflow would ignore `test_shape_builder` tests for now and it wouldn't interrupt the entire workflow
