* Move initialisation of variables like nixConfDir from libmain to

  libstore so that the Perl bindings can use it as well.  It's vital
  that the Perl bindings use the configuration file, because otherwise
  nix-copy-closure will fail with a ‘database locked’ message if the
  value of ‘use-sqlite-wal’ is changed from the default.
