#782: When building a plan, use installed package dependencies in preference to
those from Hackage

Comment(by duncan):
The dep planner does prefer installed packages to source ones, but not
quite in the simple way you expect. This is a misfeature of the rather
naive constraint solver algorithm that we're currently using. The solver
is slated for a rewrite (to support the private dependencies feature) and
hopefully this issue will be taken care of at the same time.
