Dongsu Park 70b15a8ffb .github: migrate to SDK container based Github Actions ...

Now that Flatcar SDK does not support cork of mantle any more,
we need to migrate the Github Actions of coreos-overlay to the
new container SDK based approach.

Simply download a container image of the latest Flatcar release,
run the container, generate patches from there.

Note, since the Flatcar scripts repo of LTS-2021 still does not
have necessary Container SDK scripts like run_sdk_container, we
need to skip checking out a specific base branch in case of
LTS-2021.
