[PATCH] 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.
