We use dedicated docker container as builder and we are able to clean
data inside only by re-creating of it. Let's add disk usage and clean
commands for builder.

We cannot build for another arch after building for one arch because of
setting skipBuild to true if one arch found. In other words "linuxkit
pkg build --platforms linux/riscv64,linux/amd64 ..." after "linuxkit pkg
build --platforms linux/amd64 ..." will not build for linux/riscv64
which is not expected.
In general when we check for available images and able to found part of
platforms we do not want to rebuild all of them. So this PR includes
platformsToBuild slice which we fill with platforms we want to build for
.

It is not easy to use cross-platform build with CGO enabled so lets
allow build without cgo for darwin and use virtualization framework only
if we built with CGO.

If we cannot open file for some reason it is better to skip it instead
of exit. Also we should skip symlinks and directories.

We should expand the list of supported arches to be able to build them if we want. Without this we will stuck on sending tarball during build for riscv64.

To be able to identify successive file changes without commit, we should
use their hash in tag alongside with dirty flag
(<ls-tree>-dirty-<content hash>).

We pull all arches for the image which is suboptimal in terms of storage
consumption. Let's pull only required platforms.

We check only for existence of builder container and do not start it in
case of not running state. We should start it for example after reboot
of node to be able to build something.

We noticed that we use host arch when we want to use previously build
image in oci-layout. Let's use fix on buildkit side and improve test.

We should check if we have args in "FROM" and replace them:
ARG IMAGE=linuxkit/img
FROM ${IMAGE} as src
will be parsed as
FROM linuxkit/img as src

We do not allow to load into docker images that are targets another
platform differ from current arch. Assume this is because of no support
of manifest. But we can keep all images in place by adding arch suffix
and using tag without arch suffix to point onto current system arch. It
will help to use images from docker for another arch.
