Rebuilding the integration test every time is very slow. Let's introduce a way to iterate on an integration test without rebuilding the image every time. By making a btrfs snapshot before we run the integration test, we can then systemctl soft-reboot after running the test to restore the rootfs to a pristine state before running the test again. As /run/nextroot will get nuked on reboot or soft-reboot, we introduce a tmpfiles snippet to make sure it is recreated every (soft-)reboot and adapt the existing tests to deal with this new symlink.
