Hi Guix! This patch adds an SSH server to the installation image
to aid remote installations as requested in
https://lists.gnu.org/archive/html/help-guix/2017-01/msg00047.html

lsh-service depends on networking, so I pulled in a DHCP client too.
It increases the image size by about 29MiB.

* gnu/system/install.scm (%installation-services): Add DHCP-CLIENT-SERVICE
and LSH-SERVICE.
