installer: keymap: Fix optional fields handling.
Fixes: <https://issues.guix.gnu.org/50723>. The keymap xml contains optional shortDescription and description fields. The assoc-ref call on those fields can return false, handle it correctly. * gnu/installer/keymap.scm (xkb-rules->models+layouts): Introduce a new "maybe-empty" helper to deal with optional fields. Use it for shortDescription and description fields.
