    build: always set CONFIG_IPV6
    
    Disabling this build tunable breaks build and seems unrealistically
    likely to be fixed.
    
    This patch sets the related CONFIG to always true and removes the
    config prompt, keeping the change minimal, and, should !CONFIG_IPV6 ever
    be fixed, easy to revert.
