Swap order of discovering of -ltinfo and -lterminfo

[krytarowski]

Summary

NetBSD ships with native curses(3) and -ltinfo is a part of ncurses.
Set -lterminfo before -ltinfo, as it allows to prioritize native curses
libraries. Mixing curses and ncurses does not work well, especially
in software built on top of llvm.

Original patch by Ryo Onodera (NetBSD) in pkgsrc.

LGTM. There's no terminfo on Linux (or majority of other systems, I suppose), so this shouldn't break anything. I've tested it on Linux, tests pass and there's no perceivable difference ;-).

[dim]

On FreeBSD, there is no libterminfo either, so LGTM.
