Bug#251115: kbd-chooser: Wrong default map for nl_NL

[Frans Pop <aragorn@tiscali.nl>]

Package: kbd-chooser
Version: 0.50

With build 20040526 (i386 netinst CD), when I choose language nl_NL, I 
suddenly get 'Belgisch (be-latin1)' as the default keymap.
This is very, very wrong: no-one has a Belgian keyboard in the Netherlands!

20040522 had 'Dutch' as default; I wonder how this got changed.

Note: This may be different in SVN or sid_d-i, as I requested in #250548 to 
have 'US American' as default for Dutch and I got a reply the change had been 
made in the console-data repository.

I would very much appreciate it if this could be fixed for RC1!
