ncurses: Fix pkgsrc check and use of ncurses

Without the macro SET_NEED_WCHAR_H defined, the ncurses header will not
include wchar.h which is where the wint_t type is defined.  This breaks
any program loading ncurses.h without defining this macro because several
functions use the wint_t type.

Define wint_t as int if wchar.h isn't included.  This fixes the ncurses
check on several pkgsrc configuration checks and allows the package to
build with the system ncurses.
