libstore: have makeLocalDerivationGoal return unique_ptrs

these can be unique rather than shared because shared_ptr has a
converting constructor. preparatory refactor for something else
and not necessary on its own, and the extra allocations we must
do for shared_ptr control blocks isn't usually relevant anyway.
