Add rxvt-unicode terminfo, required by rxvt-unicode to function properly.

Providing this in ncurses makes it widely available, much better than having to
install rxvt-unicode everywhere.

http://bugs.gentoo.org/show_bug.cgi?id=192083

This patch uses the updated rxvt-unicode-9.09 terminfo
which adds support for 256 colors.
