policy and daf modules: fix reroute rules

See merge request !901

Well, the part about giving semantics to nil actually
decreases strictness.

In finish() phase DONE is (almost?) always set, so it didn't make sense.
The mistake came from c16728f5 !678.

It was possible for some failures to disappear that way.

Well, the `view` note applies to any sockets passed from a supervisor,
but together that seems a very exotic combination.

In some environments, e.g. VMs, even the IPv6 loopback may
not be available. Using freebind allows the service to start up with
default configuration without requiring the user to change interfaces.

The services appear to be restarted on CentOS 7.

The preconfig is used to set distro-specific values to avoid messing
with user config, in partciular:

- binding to control sockets under systemd
- setting default cache location

- meson templating no longer needed
- commented out DoH/webmgmt configuration removed
- added explicit port 53 and kind=dns

These addresses have been deprecated for quite some time,
and this month they were even shut down.
