[kbd] Canadian multilangual keymap

Hi,

I am from Québec and I use the canadian multilangual keymap in the tty linux
terminal. There has been a AUR package
(https://aur.archlinux.org/packages/ca_multi/) for some time now for people like
me that use the same keymap. There are a lot of people that use this keymap here
in Québec. I think that it should be a good idea to provide it in the official
package as it would be nice to arch beginners from Québec that want to jump in.

You will be able to find the keymap inside the tarball downloadable at the URL I
previously pasted.

Cordially,

Simon Désaulniers
