Note that since an output derivation has always type output, while
something added by addToStore can have type output or source depending
on the hash, this means that the same input can be hashed differently
if added to the store via addToStore or via a derivation, in the sha256
recursive case.
It would have been nicer to handle fixed-output derivations under
"source", e.g. have something like "source:<rec><algo>", but we're
stuck with this for now...
