    unattended-file: Prefer cdrom over floppy as injection method
    
    Instead of using "floppy" as the way to perform unattended installations
    for Windoes, let's prefer using "cdrom" instead.
    
    The main reasons behind this change are:
    - VMs using q35 may have floppy device disabled in some systems;
    - We can drop mtools dependency;
    
    Generating the ISO depends on genisoimage, tho. However, it's not a big
    deal as genisoimage is already a GNOME Boxes dependency.
