[aur-general] Please delete cairo-tee and cairo-xcb-tee

[Oon-Ee Ng]

cairo in [extra] already has tee support.

cairo-tee[1] and cairo-xcb-tee[2] can be deleted. Maintainer for [2]
has said as much, and [1] has no maintainer since the previous
maintainer disowned it once [extra] got cairo with --enable-tee.

[1] http://aur.archlinux.org/packages.php?ID=45693 is cairo-tee
[2] http://aur.archlinux.org/packages.php?ID=45772 is cairo-xcb-tee
