Subject: [PATCH 2/2] keylayouts: don't print "Unknown key" message

on keyboards with stuck keys, this results in GRUB just
spewing it repeatedly, preventing use of GRUB.

in such cases, it's still possible to use the keyboard,
and we should let the user at least boot.

it often appears when people plug in faulty usb keyboards,
but can appear for laptop keyboards too; one of my e6400
has stuck keys.

with this patch, grub should be a bit more reliable in
terms of user experience, when the keyboard is faulty.
