Changes from previous version:
* Service initialization is reduced to just creating the "/etc/dropbear"
directory.
* The initialize and host-key options are removed.
* The -R flag has been added to dropbear.

Example service file:
```scheme
(use-modules (gnu))
(use-service-modules base networking ssh)

(operating-system
  (host-name "test")
  (timezone "Europe/Zurich")
  (locale "en_US.UTF-8")

  (bootloader (grub-configuration (device "/dev/vda")))

  (file-systems (cons
    (file-system
      (device "/dev/vda1")
      (mount-point "/")
      (type "ext4"))
    %base-file-systems))

  (users (cons
    (user-account
      (name "test")
      (group "users")
      (supplementary-groups '("wheel"))
      (home-directory "/home/test")
      (password "sa5JEXtYx/rm6")) ;; password pass
    %base-user-accounts))

  (packages %base-packages)

  (services (cons*
    (dhcp-client-service)
    (dropbear-service
      #:port-number 22
      #:allow-empty-passwords? #t
      #:root-login? #t
      #:syslog-output? #t
      #:pid-file "/var/run/dropbear.pid"
      #:password-authentication? #t)
    (rngd-service)
    %base-services)))
```

Additional information:

This patch is needed, just adding -net user,hostfwd=tcp::10022-:22 at the end
didn't work for me.

```diff
```

You can use this command to connect to dropbear:

ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no test@localhost -p 10022

I'm currently having an issue with all guix operations after commit 4ee96a7 but I
tested it with previous commits. I'm assuming that the problem is related to nixos
and that it shouldn't affect people using guixsd.

David Craven (2):
  gnu: lsh: Move to (gnu packages ssh)
  services: Add 'dropbear-service'.
