This adds support for a runtime configuration file that can do:
- `mkdir` to make a directory at runtime, eg in `/var` or `/tmp`, to avoid workarounds
- `interface` that can create network interfaces in a container or move them
- `bindNS` that can bind mount namespaces of an `onboot` container to a file so a service can be started in that namespace.
It merges the `service` and `onboot` tools (in `init`) to avoid duplication. This also saves some size for
eg LCOW which did not use the `onboot` code in `runc`.

This uses a more memory efficient copy, and gets us closer to
not having a shell in the base system if not required.

This commit moves the include statement to the bottom of the file to
ensure that all variables are set before conditionals are evaluated.
I also changed the ifndef NETWORK to ifdef NETWORK as the former was
incorrect. We want `NET_OPTS="--network=none"` in cases where NETWORK is
not defined.
Fixes: #2134

These now inherit from a top-level package.mk
Options like use of the network can be enabled on a per package basis
This removes a lot of duplicate code and make the maintenace of these
Makefiles much easier

The binary is used in tandem with CONFIG_STATIC_USERMODEHELPER=y in 4.11+,
see the big comment in the binary for the current whitelist of binaries.

We only need the alpine-baselayout packe to run init. This also
removes the sha256 import from alpine:edge.
This also reduces the size of the init package by more than
50% to just 1.5MB.
Also make the HUB org/registry build time configurable.

There is no need for start-stop-daemon since this package
is using containerd. Remove it and update the init
package to alpine:edge
Also use the git tree hash for the package hash while at it.

Also add ca-certificates to base, needed to use `dist` to pull.
Make two stage builds for `containerd` and `runc` so they have a
from `scratch` second stage.

This is compatible with containerd 8353da59c6ae7e1933aac2228df23541ef8b163f
which was picked up by d2caae4c1a.
This required jiggering with riddler output some more to update to new OCI
config.json format for capabilities.

Since Makefile contains the hashes we need a dependency otherwise changing the
hashes does not necessarily result in the binaries getting updated.

- now supports image pull and run end to end
- update runc to last version before spec update fix#1302
- remove ext2 utils from init
