Fix hr keyboard in 7.0

As always, hr_US keyboard is broken (again) in 7.0.
However, problem is easily solved this time (just one line diff), at least
under Debian:

+    include "us"
     name[Group1]= "Croatia - US keyboard with Croatian letters";
     key  { [    any,    any,	backslash	        ] };

You should note that xkb files moved to /usr/share/X11/xkb/symbols
and that keyboard can be activated using:

$ setxkbmap hr us

Update: Ante Karamatic noted that same fix is already in
upstream code.
To be honest, fix was to include us and not latin symbols,
so that's also corrected in this post.
