build-sys: remove global dependence between widechar and ncursesw

It seems that globally defined dependence between ncursesw and
wide-char support is overkill, because in some cases (e.g. cal(1)) we
can use ncurses independently on wide-char support.

It would be better to care about relation between wide-char and
ncurses individually (per util).
