    libxl: 9pfs has a QEMU backend
    
    Add 9pfs to the kind of PV drivers that has a QEMU backend, specifically
    to the macro QEMU_BACKEND.
    
    This is needed otherwise upon domain destroy we get a timeout error:
    
    libxl: error: libxl_device.c:1132:device_backend_callback: Domain 1:unable 
to remove device with path /local/domain/0/backend/9pfs/1/0
    libxl: error: libxl_domain.c:1129:devices_destroy_cb: Domain 
1:libxl__devices_destroy failed
    
    This change should have been part of b53b4037cef6 "libxl/xl: add support
    for Xen 9pfs".
    
    Also add a comment in libxl_types_internal.idl to help remember changing
    QEMU_BACKEND going forward.
