Log Message:
weechat: make curses detection logic handle netbsd curses, at the possible
expense of causing problems due to pkgsrc infrastructure not hiding a base
curses well enough.

We now search in the following order:
ncursesw, curses, ncurses.

With cmake under pkgsrc, it will search your /usr/lib, so I don't have a
way to hide a base curses if requested to do so.

if you're trying to use pkgsrc ncurses and have a base curses, this
will use your base curses.

bump pkgrevision.
