nixos/containers: give a name to an anonymous container module

Browse source 
See https://github.com/NixOS/nixpkgs/issues/15747. Previously this module was called `<unknown-file>`
in error messages, now it is called a bit more close to real:
```
module at /home/danbst/dev/nixpkgs/nixos/modules/virtualisation/containers.nix:470
```
