    access-file: don't use FamilyLocal for auth cookie
    
    FamilyLocal is really fragile to hostname changes, so
    avoid using it when creating the initial auth cookie for
    establishing access to the X server for the slave.
    
    This commit changes the Xauthority entry to use FamilyWild
    which makes the address of the entry unimportant.
