    BUG/MINOR: cli: correctly handle abns in 'show cli sockets'
    
    The 'show cli sockets' was not handling the abns sockets. This is a
    problem since it uses the AF_UNIX family, it displays nothing
    in the path column because the path starts by \0.
    
    Should be backported to 1.9 and 1.8.
