test: store coredumps in journal
    
    To make debugging much easier, especially for crashes in tests under
    QEMU, let's store the entire coredump bundle in the systemd journal,
    which is usually kept around by various CIs. Right now, we usually end
    up with a journal, but without the coredump itself, which is pretty
    useless.
