daemon: Fix several format strings.

This is a followup to 3af52f845fe2ceb448416ac7b9f48925673c594e and
6f1448ef89c8ad29e2a479099531fd3a87701e46.

* nix/libstore/local-store.cc (LocalStore::queryValidPathId): Change %1% to {}.
* nix/libstore/optimise-store.cc (LocalStore::optimisePath_): Likewise.
* nix/nix-daemon/guix-daemon.cc (open_unix_domain_socket): Likewise.
(main): Likewise.
* nix/libutil/affinity.cc (restoreAffinity): Remove useless %1%.
