We were using Debian but Alpine more consistent. Use nested build.
Currently extract the hash in a nasty way but this can be fixed later
when we switch over hashing method.

This was missed when things were renamed.
The intention with this code was (apparently) to provide a (pseudo)unique
hostname in the case where something more specific was not provided (e.g. by
DHCP). Make this a little clearer by using '(none)' rather than 'linuxkit' as
the default, in the normal case this will be overwritten by something more
specific and if it isn't we will change it to something somewhat unique derived
from the MAC address (as before). nb: '(none)' is already used by Debian so I
think it is a safe choice as the sentinel value.
The use of both CONFIG_DEFAULT_HOSTNAME and the explicit /etc/hostname from
mkimage.sh is likely to be redundant in some cases, but neither seems to
completely cover all cases so keep both.

We had serveral files with instructions, in particular for
networking, for macOS/Docker for Mac. Let's have just one place.

This currently only changes the `gcp` target, but is the new
model - the `build` command will only do things locally, then
you need to `push` to an image store such as GCP or other ones
in order to `run` for platforms that cannot boot directly from
a local image.

Previously only `/var` was `rshared` but some people need to share
mounts in `/opt` etc so let us make everything `rshared` for now.

This uses the Packet.net API and iPXE to boot a Moby host.
There are several enhancements coming soon, such as SSH key
customisation, but this PR is sufficient to boot a host and
then use the web interface to get console access.
The user must currently upload the built artefacts to a public
URL and specify it via --base-url, e.g.:
moby run packet --api-key <key> --project-id <id> \
--base-url http://recoil.org/~avsm/ipxe --hostname test-moby packet

The DHCP client updates /tmp/etc/resolv.conf and this needs
to be bind mounted into the other containers.

The sha1 tag should be sufficient to uniquely identify the image
and the sha256 versions are just very long...

This is needed for cloud environments that want to get their metadata in
the onboot phase over the network.

Added to Docker example as Swarm mode likes time sync.
Note uses pool.ntp.org at present, on some providers it
should use a different source.
Constraints not enabled as they seem to have an issue;
possibly trying to set before network is up.

Instead of mounting a new filesystem, revert to doing a `rw` bind.
However do not make `/` `rshared`, just `/var` as that is where we expect
filesystems to be mounted for persistence. Also only make the actual
container rootfs writeable, not the whole directory.

A few YAML files include the binfmt container, where it's not really
needed. Remove it to make the samples simpler.

As suggested by @shykes these are clearer
- onboot for things that are run at boot time to completion
- services for persistent services

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