The msdos partitioning now handles more then 4 partitions by inserting
an extended partition. To test this doesn't confuse the gpt partitioning
expand that test to more then 4 partitions as well.
The docker-compose test strategy was mainly done for integration with
dockerhub, but as dockerhub no longer builds our images it's not that
relevant.
What's more interesting is to use the docker container we've build to
run a selection of debos recipes, whose successfull build indicate
success. This both makes it easier to test locally as well (just run the
debos recipe) and makes the test jobs more specific.
On top of the existing test this also adds a "debian" test which does some basic
debian smoketesting (debootstrap and apt) as well as a basic
"partitioning" test. The partitioning test unforutunately doesn't work
in the nofakemachine run as udev isn't available in the container, so
that only runs on UML and Qemu based backends.
Current the kvm backend isn't tested because the standard github action
runners don't support kvm. But qemu, though being lots slower, covers
some part of it.
