guix-register: Allow the initial directory creation to proceed.

This fixes a bug whereby 'guix-register' would bail out when trying to
create NIX_STORE_DIR/.links when NIX_STORE_DIR is read-only.

* nix/guix-register/guix-register.cc (parse_opt): Initialize
  'settings.nixStore' to PREFIX + NIX_STORE_DIR.
  (main): Change 'settings.nixStore' once the 'LocalStore' has been
  instantiated.
