wcwidth on AIX 7.1BETA

[Bruno Haible]

The logs say:

checking whether wcwidth works reasonably in UTF-8 locales... yes

This means that the wcwidth replacement is not necessary.

        wcwidth: Drop replacement on AIX 7.
        * m4/wcwidth.m4 (gl_FUNC_WCWIDTH): When cross-compiling, guess yes on
        AIX 7.
        Reported by Rainer Tammer.
