Previously, in Zulip voyager, the cron jobs would spew error emails
every time they ran, due to this directory not existing.
This also tightens the permissions for the folder and avoids needing
to create a nagios user for Zulip voyager; it should be writeable by
both root and the zulip user and world-readable (and thus readable by
the Nagios user on zulip.com systems).
This allows us to specify different rules for the zmirror machines, which need
ports open for Zephyr.

The /etc/init.d/iptables-persistent initfile changed to expect there to be two
files in /etc/iptables (rules.v4 and rules.v6) instead of a single rules file.
Several of our machines are currently running without iptables rules as a
result.

These are things that don't make sense to require on our local server
appliance systems.
