[PATCHv3] locale/C-translit.h.in: Greek -> ASCII transliteration table [BZ #12031]

[Diego (Egor) Kobylkin]

Changelog:

v3
 * spurious change (https/http) removed

v2
 *  ETA WITH TONOS is now transliterated as I/i to be consistent throughout the table. Ancient Greek calls for E/e and modern for I/i which we are taking here.
