Bug 57114 - regression on FcFontMatch with namelang
After 7587d1c99d9476b6dd4dbe523c0204da700fed8d applied, family,
style, and fullname is localized against current locale or lang
if any though, the string in other languages were dropped from
the pattern. this caused unexpected mismatch on the target="font"
rules.
This fix adds other strings at the end of the list.
