[gnome-boxes] libvirt-machine: Stop if guest ignores shutdown request

commit 581b43c8c0573d1d73212374dcd1e6405e97e343

    libvirt-machine: Stop if guest ignores shutdown request
    
    It is not guaranteed that guest will honor the ACPI shutdown (e.g GRUB).
    Give user the choice to force it to shutdown if VM fails to shutdown in
    5 seconds.
