runqemu-ifdown: clean up the remaining iptables rules
The iptables rules for the tap interface are added by runqemu-ifup
everytime we use runqemu to start a qemu target. But it's not cleaned
up when runqemu exits.
This patch cleans up the remaining iptables rules for the tap interface
in runqemu-ifdown.
