This commit adds a smoke test that builds the ibcli container
and runs a fedora-41 raw-minimal build to double check that
the container based building actually works.
Thanks to Ondrej for suggesting this.
Automatically build the container for `image-builder-cli` and upload it
to `ghcr.io`. This builds only for x86 initially.

This commit adds a basic HACKING.md that explains the bare mimimum
to get started, including `go test -short` to skip the expensive
tests.
Contains also a drive-by rename of the test dependency install
for the GH action.
