Florian Klink 0c1801b489 dovecot: add dovecot_pigeonhole to system packages
`sieve-test` can be used to test sieve scripts.

It's annoying to nix-shell it in, because it reads the dovecot global
config and might stumble over incompatible .so files (as has happened
to me).

Simply providing it in $PATH is easier.

Quick Start

   { config, pkgs, ... }:
   let release = "nixos-21.11";
   in {
     imports = [
       (builtins.fetchTarball {
         url = "https://gitlab.com/simple-nixos-mailserver/nixos-mailserver/-/archive/${release}/nixos-mailserver-${release}.tar.gz";
         # This hash needs to be updated
         sha256 = "0000000000000000000000000000000000000000000000000000";
       })
     ];

     mailserver = {
       enable = true;
       fqdn = "mail.example.com";
       domains = [ "example.com" "example2.com" ];
       loginAccounts = {
           "user1@example.com" = {
               # nix-shell -p mkpasswd --run 'mkpasswd -sm bcrypt' > /hashed/password/file/location
               hashedPasswordFile = "/hashed/password/file/location";

               aliases = [
                   "info@example.com"
                   "postmaster@example.com"
                   "postmaster@example2.com"
               ];
