Method BRepBuilderAPI_MakeShape::EnsureToleranceRule was made slightly

simpler.

Tolerance post Build (Perform) fix was made for:
- BRepAlgoAPI_BooleanOperation,
- BRepFeat_MakePrism,
- BRepOffsetAPI_MakePipeShell.

Draw command getsourcefile now returns result for:
- buildsweep,
- simulsweep,
- geompipe.
