Bug#183365: kbd-chooser: Default keyboard should be american (us) not dvorak

[Petter Reinholdtsen <pere@hungry.com>]

Package: kbd-chooser
Version: 0.0.10

When installing using DEBCONF_PRIORITY=high, the keyboard will switch
from american layout to dworak layout.  I tracked this down to the
fact that kbd-chooser will use dworak as the default keyboard layout,
but not display the question and just change the layout.  Not
displaying the question when using DEBCONF_PRIOTITY=high is very good,
but I believe the default should be either not to touch the current
layout (which is american by default on all machines I have tested),
or to set american layout by default.  Using dworak as the default
layout is not good.
