Message:

ncurses: Modify the header to always use the ABI of ncursesw

instead of the 8-bit ncurses.

We don't provide the 8-bit ncurses library and we are "faking" it using
ncursesw. Thus innocent package may be compiled with the 8-bit ABI
(because it does not know what we are doing and so it does not use
the "expected" preprocessor definitions to enable the wide ABI) but
linked against ncursesw, causing a potential ABI mismatch.
