keymap: Add back a tiny utility for setting the system keyboard layout

This patch removes the setuid-root flag from the KeyboardSettings GUI
application and adds back the old "keymap" program.

It doesn't feel very safe and sound to have a GUI program runnable
as setuid-root, so in the next patch I'll be making KeyboardSettings
call out to the "keymap" program to do its bidding.
