    jail: set default root directory for a jail to its parent's root.
    
    All default jail parameter values are an empty or otherwise standard
    value, or are copied the jail's parent.  A notable exception is the
    root directory, which is instead copied from the creating process's
    jail.  Fix that to be in line with everything else.
    
    This change affects only the default when no path is specified; if
    a path of "/" is explicitly given, that will still be the creating
    process's root directory.
