Run gateway plugin as OCI container via runc

[justinmoon]

@dpc was just telling me how you can make an executable shell script that executes a ln_gateway OCI container with the runc container runtime. This could behave exactly like a normal executable, but could run on any distro that has runc installed.

Alternative to #1008 for making CLN plugin run on all linux distros.

[dpc]

#!/usr/bin/env bash

exec podman run $MOUNT_OPTS_ETC -q -i docker.io/fedimint/ln-gateway "$@"

This behaves very much like we were running ln_gateway process itself: stdio, stdout, stderr, etc. Though I'm hitting containers/podman#14707 which makes ctrl+c not work.

Might try other stuff later too.

@justinmoon @elsirion Once #1452 lands, please create ln-gateway docker hub repos, so we can upload it there.

Done

Bundling the binary like in #2036 seems to render this too much hassle.
