Fix QFontconfigDatabase unable to fallback to a localized family
When populating the font database, FcPatternGetString(FC_FAMILY) gets
a localized font family name; but, in fallbacksForFamily, it gets
a non-localized font family name, so it unable to find the proper font to fallback.
Simply register all family name variants as aliases to localized name
and make sure they are checked when getting fallback families.
