            Log:
            Drop the use of -set-cookie since it is unsafe.

Also, configure the ejabberdctl script to set INSTALLUSER so it
uses su to be ejabberd (#1163812).

-Subject: [PATCH] Use -set-cookie when running erl in ejabberdctl.template.
-
-This patch converts the ejabberdctl.template to use erl's
--set-cookie option when an .erlang.cookie file is found in
-$SPOOL_DIR. This will help for installations where ejabberd might
-be started by one user, but ejabberdctl might be used by a
-different user to manage it. For example, in Fedora ejabberd is
-launched by systemd as the ejabberd user, but users might want to
-use "sudo ejabberdctl" to manage the node.
