Add script to change the keyboard layout.
Personally I'm used to the US keyboard, but Libre En Communs has other sysadmins than me and they might want to use their preferred keyboard layout instead. This script has been tested on a Guix system installation. Finding a way to launch the script at boot will be done later on. Signed-off-by: Denis 'GNUtoo' Carikli <GNUtoo@cyberdimension.org>
