Using the label `org.mobyproject.config` will use that JSON
(or yaml, but it is very hard to get yaml into a label as newlines are
not respected) for parameters that are not explicitly set in the yaml file.
Had to change parameter definitions so override behaves as expected.

Add a canonical single tarball output format. This
adds kernel and cmdline to `/boot` where LinuxKit output
formats will find them.
Make the other output formats use that as a base.

`docker create` will not pull an image so we need an additional fallback.
Rework the pull and trust code so it is in one place to facilitate this.

Also do not require `tar` to be in container, use the standard
image export code that we already have and find the files we
want.
