redlib.tests: fix eval

Without the change the eval fails as:

    $ nix build --no-link -f. redlib.tests
    error: attribute 'redlib' missing
       at pkgs/by-name/re/redlib/package.nix:50:26:
           49|   passthru.tests = {
           50|     inherit (nixosTests) redlib;
             |                          ^
           51|   };
       Did you mean redis?
