    libxl: Have READ_LIBXLDEV use libxl_path rather than be_path
    
    Fix the just-introduced bug in this macro: now it reads the
    trustworthy libxl_path.  Change the variable name in the two functions
    (nic and channel) which use it.
    
    Shuffling the bump in the carpet along, we now introduce three new
    bugs: the three call sites pass a backend path where a frontend path
    is expected.
    
    No functional change.
    
    This is part of XSA-178.
