config: 10.interface: search "ethtool" in $PATH instead of using a hardcoded path

This is very useful for testing, I use such a script:

cat ~/bin/ethtool
 #!/bin/sh

 IFACE=$1

 case "$IFACE" in
        Neth2)
                ;;
        Neth3)
                ;;
        Neth4)
                ;;
        Neth5)
                ;;
        *)
                exec /usr/sbin/ethtool $@
                ;;
 esac

 ip link set down $IFACE

 exec /usr/sbin/ethtool $@
