drop ambiguous-wide behaviour from Unicode CJK locales

Thomas Wolff
It seems that ambiguous-wide behaviour (i.e. double-width property for
characters in the East Asian Ambiguous width category) for CJK locales
with UTF-8 encoding is inconsistent with Linux locale definitions.
I've sent a patch to the newlib list that changes that. Characters like
─ ü æ are no longer wide in the following locales:
ja_JP.utf8
ko_KR.utf8
zh_*.utf8
but only in ja, ko, zh locales with legacy encoding. Explicit modifiers
@cjkwide and @cjknarrow are not affected.
