My patch for having Right Control Key work fine in Canada ("ca" keyboard)

Hi !

I'm using "ca" keyboard, and was tired that this right control key was mapped 
to some 5th modulator key that's seems completely useless...
So I patched "/etc/X11/xkb/symbols/ca", with the following patch of my own, 
and it works perfectly fine. I think many people would appreciate this to be 
the default.

<     key <RCTL> {        [ ISO_Level3_Shift              ]       };

<     modifier_map Mod5   { <RCTL> };
---
> //    modifier_map Mod5   { <RCTL> };

<     modifier_map Control{ Control_L };

>     modifier_map Control{ Control_L , Control_R };
