[BuildSystem] Fix build() to return false if the build aborts.

 - Currently the only thing which can cause an abort is discovery of a cycle by
   the core engine. This should most likely be modeled in a different fashion,
   but for now this at least lets clients know when the build graph was not
   completed traversed.
