Ludovic Courtès c62f8ab11f derivations: ‘derivation-build-plan’ returns builds in topological order. ...

That makes ‘derivation-build-plan’ directly usable in cases where one
wants to sequentially build derivations one by one, or to report builds
in the right order in the user interface.

* guix/derivations.scm (derivation-build-plan): Wrap ‘loop’ in
‘traverse’.  Perform a depth-first traversal.  Return the list of builds
in topological order.
* tests/derivations.scm ("derivation-build-plan, topological ordering"):
New test.
