Puppet _always_ sets the `+x` bit on directories if they have the `r`
bit set for that slot[^1]:

As such, for instance, `0640` is actually applied as `0750`.
Fix what we "want" to match what puppet is applying, by adding the `x`
bit. In none of these cases did we actually intend the directory to
not be executable.

The `needrestart` tool added in 22.04 is useful in terms of listing
which services may need to be restarted to pick up updated libraries.
However, it prompts about the current state of services needing
restart for *every* subsequent `apt-get upgrade`, and defaulting core
services to restarting requires carefully manually excluding them
every time, at risk of causing an unscheduled outage.
Build a list of default-off services based on the list in
unattended-upgrades.
Our current EC2 systems don’t have an interface named ‘eth0’, and if
they did, this script would do nothing but crash with ImportError
because we have never installed boto.utils for Python 3.
(The message of commit 2a4d851a7c made
an effort to document for future researchers why this script should
not have been blindly converted to Python 3. However, commit
2dc6d09c2a (#14278) was evidently
unresearched and untested.)

This means that services will only open their ports if they are
actually run, without having to clutter rules.v4 with a log of `if`
statements.
This does not go as far as using `puppetlabs/firewall`[1] because that
would represent an additional DSL to learn; raw IPtables sections can
easily be inserted into the generated iptables file via
`concat::fragment` (either inline, or as a separate file), but config
can be centralized next to the appropriate service.

This provides a single reference point for all zulip.conf settings;
these mostly link out to the more complete documentation about each
setting, elsewhere.
Fixes#12490.
