[PATCH v2] meson: fix ncurses detection on macOS

[Chris Hofstaedtler <chris@hofstaedtler.name>]

Without this, meson fails with "curses package not usable" when using ncurses
6.2. Apparently the wide functions (addwstr, etc) are hidden behind the extra
define, and meson does not define it at that detection stage.

Regression from b01a4fd3bd7d6f2 ("configure: Define NCURSES_WIDECHAR if we're
using curses"). The meson conversion has seen many iterations of the curses
check, so pinpointing the exact commit breaking this is not so easy.
