kbd: Rename some keymaps.

From upstream kbd, some keymap names are reused across very different
keyboard layouts. This is a a problem because loadkeys just picks the
first keymap it sees. The clashing names lead to e.g.  "loadkeys no"
defaulting to a norwegian dvorak map instead of the much more common
qwerty one.

Used Arch Linux's list of keymaps that need renaming, with a small
deviation: the norwegian dvorak map becomes dvorak-no instead of
no-dvorak, to match the naming scheme for all the other dvorak maps.
