Fix two bugs in reboot tests

Browse Source 
First, "ifconfig eth0 down/up" on Ubuntu and Debian breaks
connection to the instance, thus tests after this one all fail.
Second, replacing appending iptable rules with inserting them on
the top of iptables, otherwise the tests may fail if iptables
are not empty.
