    libxl: clean up qemu-save and qemu-resume files
    
    These files are leaked when using qemu-trad stubdom.  They are
    intermediate files created by libxc. Unfortunately they don't fit well
    in our userdata scheme. Clean them up after we destroy all userdata,
    we're sure they are not useful anymore at that point.
