nixos/dwm-status: use structured RFC42 style settings (#416212)

- The `services.siproxd` module has been removed as `siproxd` is unmaintained and broken with libosip 5.x.

- `services.dwm-status.extraConfig` was replaced by [RFC0042](https://github.com/NixOS/rfcs/blob/master/rfcs/0042-config-option.md)-compliant [](#opt-services.dwm-status.settings), which is used to generate the config file. `services.dwm-status.order` is now moved to [](#opt-services.dwm-status.settings.order), as it's a part of the config file.

- `renovate` was updated to v40. See the [upstream release notes](https://github.com/renovatebot/renovate/releases/tag/40.0.0) for breaking changes.

- The Postfix module has been updated and likely requires configuration changes:

let

  cfg = config.services.dwm-status;

  order = lib.concatMapStringsSep "," (feature: ''"${feature}"'') cfg.order;

  format = pkgs.formats.toml { };

  configFile = pkgs.writeText "dwm-status.toml" ''

    order = [${order}]

    ${cfg.extraConfig}

  '';

  configFile = format.generate "dwm-status.toml" cfg.settings;
