Maximilian Bosch 205c59367c libstore: add genGraphString from why-depends
This will be useful for other things as well such as the
disallowedRequisites error in the builder code. Additionally, print the
dependencyPath in the tree bold to spot where a change terminates.

Also implemented some unit-tests for this code.
