Subject: [PATCH 3/3] nixos/zmap: init module

The module installs `zmap` globally and links the config files to
`/etc/zmap`, the default location of config files for zmap.

The package provides pretty much a sensitive default, custom configs can
be created like this:

```
{ lib, ... }:
{
  environment.etc."zmap/blacklist.conf" = lib.mkForce {
    text = ''
      # custom zmap blacklist
      0.0.0.0/0
    '';
  };
}
```
