    tools/ocaml: Delete the Xenctrl.with_intf wrapper
    
    This wrapper hides an opening and closing of the xenctrl handle, which 
amongst
    other things opens and closes multiple device files.
    
    A process should create one handle at the start of day and reuse that; 
indeed
    there is no guarentee that the process will retain sufficient permissions to
    re-open /dev/xen/privcmd at a later point.
    
    With the final user of Xenctrl.with_intf removed, drop the wrapper entirely.
