The `cp -a lbi/usr/. /usr` command was preserving local directory
permissions which in one case for me have a restrictive mode 0750
which breaks booting.
Switch to `install -D -m 0644` which explicitly sets file modes and
creates parent directories with correct 755 permissions, while also
simplifying the directory structure.

A key thing for me is that the `Justfile` should be a one-stop
shop for development of the project. It can't have everything but
it should answer the basic questions of "how do I build and test
this project".
This aligns the recently added tmt-on-GHA flow a *bit* more closely
with some of that. Biggest is to use the `just build-integration-test-image` as the canonical
way to build a container image with our testing stuff in it;
which uses our main Dockerfile
Other cleanups:
- Change test script to move into tests/tmt/ as a workaround for
https://github.com/teemtee/tmt/pull/3037#issuecomment-3259585271
- Change the qemu logic to use SMBIOS credentials so we don't
have to carry around both a disk image and a SSH key
- Change qemu to use `-snapshot` so we can reuse disks
- Change the scripts to accept data via argv[1] and not environment
- Drop the hardcoded testing directory and use `target/` as
a generic build artifact dir
