[gdm-list] Avoid Duplicate language names for locales that uses different scripts

[Parag Nemade <pnemade redhat com>]

Hi all,
In F-11 gdm language selection list, I found that for locales ks_IN and 
ks_IN devanagari are showing same language name "Kashmiri (India)". Both 
of these locales are for India country but divided based on scripts. 
ks_IN uses Perso-Arabic script whereas ks_IN
devanagari uses Devanagari script.

Can we have some way to identify which locale is selected or Can we have 
some kind of change in gdm language list?  I have added screenshot for 
gdm language selection list at bug 
https://bugzilla.redhat.com/show_bug.cgi?id=502778.
Please ask for more information if needed.

Thanks & Regards,
Parag,
