[Bug libc/3362] New: wcwidth() defined only for XOPEN_SOURCE

["pasky at suse dot cz" <sourceware-bugzilla at sourceware dot org>]

wcwidth() is defined only if _XOPEN_SOURCE but since according to opengroup.org
wcwidth() is defined also by POSIX 200112L, it should be defined in the case
_POSIX_C_SOURCE is set to that.

(I'm not sure why we don't define __USE_XOPEN when we define __USE_XOPEN2K,
though - that would make more sense to me.)
