Subject: [PATCH] treewide: libressl.nc -> netcat
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Quote from NixOS 25.11 release notes:

> `meta.mainProgram` is now used to determine the `NIX_MAIN_PROGRAM` environment variable. This means that changing it can now lead to a package rebuild.

And `netcat` is:

```
 netcat = libressl.nc.overrideAttrs (old: {
   meta = old.meta // {
     description = "Utility which reads and writes data across network connections — LibreSSL implementation";
     mainProgram = "nc";
   };
 });
```

`netcat` and `libressl.nc` are 2 different derivations now, use just one
 of them in nixpkgs for consistency.

This also fixes lots of warnings if `virtualisation.libvirtd.enable = true`:

```
pkgs.buildEnv warning: colliding subpath (ignored): `/nix/store/1mcayh9rmxmjcbmm6swkkyr59rjl66vc-libressl-4.2.1-nc/bin/nc' and `/nix/store/x1vmfpisbd494yykmvjkhvh3dplsnjhg-libressl-4.2.1-nc/bin/nc'
...
```
