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-&gt;models+layouts): Introduce a new
"maybe-empty" helper to deal with optional fields. Use it for shortDescription
and description fields.
