    package: ethtool: specify just one default variant
    
    Inadvertently defining 'DEFAULT_VARIANT' on both ethool and
    ethtool-full variants resulted in
    
        $ make defconfig
        tmp/.config-package.in:121615:error: recursive dependency detected!
        tmp/.config-package.in:121615:  symbol PACKAGE_ethtool-full is selected by PACKAGE_ethtool
        tmp/.config-package.in:121605:  symbol PACKAGE_ethtool depends on PACKAGE_ethtool-full
    
    Fix this by simply undefining 'DEFAULT_VARIANT' on the ethtool-full
    variant, which is ugly, but expedient.
