[patch] syscons/vt keymap: Norwegian country code conflicts with default value

Hi,

Recent changes in keymap namning for syscons/vt to use shorter names
has exposed a conflict with the value "no" both used as country code
for Norway and as a default value indicating that no keymap is set.

The attached patch proposes to use "" (empty string) as default value
instead.
