games-roguelike/dwarf-fortress: fix text mode, use ncurses-6

ncurses-compat doesn't work in DEPEND given it installs no headers,
and then it went and built against ncurses-6 then tried to load
ncurses-5 which unsurprisingly fails.

Seems to work with 6, but haven't tested much (better than entirely
broken either way).
