clang-format: rework "nm-code-format-container.sh" script
Instead of doing the broken `podman run` and `podman start` approach,
build an image ("nm-code-format:f38"), cache it, and use it to run
"nm-code-format.sh" via `podman run`. We should build and keep a
container image, not a container.

The benefit is that this allows to hand over the command line arguments
to "nm-code-format.sh". In particular the "-u" and "-F" options, which
are life savers.

This means,

  $ contrib/scripts/nm-code-format-container.sh -u

works.

Try also

  $ contrib/scripts/nm-code-format-container.sh -h

which tells you that you are running inside the container, and how to
delete/renew the container image.
