Cygwin: /proc/locales: fix sd_IN locale

Browse Source 
Due to the way locales are evaluated in Windows, we can't ask for
the script of the "sd-IN" locale, because Windows only knows the
"sd-Deva-IN" locale.  So asking for the script of the "sd" locale
returns "Arab;", because "sd" is converted to "sd-Arab-PK".

Special case "sd-IN" to workaround that issue.
