Reepca Russelstein c87a9b855e
daemon: Restore post-canonicalization permissions after moving. 
At this point the value of 'st.st_mode' is from before canonicalization, so
restoring to that will undo the permissions aspect of the canonicalization for
a top-level directory store item.

Fixes #1104, introduced in
ae18b3d9e6 (ae18b3d9e6).

* nix/libstore/build.cc (DerivationGoal::registerOutputs): update 'st' with
  post-canonicalization permissions before making actualPath
  temporarily-writable.
* tests/store.scm ("build outputs aren't writable"): new test.
