Ship podman with defaults more coherent with user expectations and
more likely to work out-of-the-box.

Deleting rules that docker has created is error-prone, because with
every update docker we have to check if anything has changed.
Cleaning up the firewall rules is part of the docker and should and must be
cleaned up and handeled by them when the service is terminated.

If docker-ce handles the firewall and fw3 is not envolved because the
rules get not proceed, then not only docker0 should be handled but also
other interfaces and therefore other docker networks.
This commit extends the handling and introduces a new uci option
`device` in the docker config firewall section. This can be used to specify
which device is allowed to access the container. Up to now only docker0
is covert.

As the protocol is set to none, this makes no sense here, as it cannot
be controlled and thus processed by the netifd.

Openwrt has a own firewall service called fw3, that supports firewall zones.
Docker can bypass the handling of the zone rules in openwrt via custom
tables. These are "always" processed before the openwrt firewall.
Which is prone to errors!
Since not everyone is aware that the firewall of openwrt will
not be passed. And this is a security problem because a mapped port is
visible on all interfaces and so also on the WAN side.
If the firewall handling in docker is switched off, then the port in
fw3 must be explicitly released and it cannot happen that the
port is accidentally exported to the outside world via the interfaces on
the WAN zone.
So all rules for the containers should and so must be made in fw3.

Up to now only the docker0 interface and bridge is created by default.
In order to create other interfaces and to integrate them into the
openwrt these functions can now be called with arguments.

procd-seccomp switched to OCI-compliant seccomp parser instead of our
(legacy, OpenWrt-specific) format. Convert ruleset to new format.

iputils upstream changed build params with version s20200821
Latest OpenWRT iputils ping now appears to report the openwrt
version tag, rather than iputils date tag
This commit sends a test ping to localhost to evaluate the
capabilities of iputils ping.

Allow `mwan3 interfaces` to get uptime via an internal function and
thus remove the dependency on rpcd for `mwan3 interface` calls.
