Subject: releng: fix broken manifest from 2.90-rc1

Well that is embarrassing. I think the proper thing is to just quickly
ship a -rc2, so I will open a backport of this.

    $ curl https://releases.lix.systems/manifest.nix
    # This file was generated by releng/create_release.xsh in Lix
    {
        aarch64-linux = "/nix/store/mrbknq000af7iaqhk53bnpk1fvfrc1xp-lix-2.90.0-rc1";
      aarch64-darwin = "/nix/store/z1bdccwsk34iv491aygh0mm1lgpf7yy1-lix-2.90.0-rc1";
      x86_64-darwin = "/nix/store/xqvfpdhzck44v6kyhgi9f8v0xybksb6a-lix-2.90.0-rc1";
      x86_64-linux = "/nix/store/h2ml0nx4477r84y82jgm8y80jpr72gqw-lix-release-tarballs";
    }
