[aur-general] Request delete of samba4-openchange

Reason: a duplicate of samba4
http://aur.archlinux.org/packages.php?ID=40043

Background:
Previous maintainer created samba4-openchange because openchange relies
on a specific version of samba4 but samba4 advanced beyond that version.
This is no longer the case, and in addition there doesn't seem to be
much use of samba4 currently except for openchange (this is also the
case in Debian/Fedora).
