xm-test: fix network13 test (protocol and extensions)
Attached there is a patch that fixes the used protocol (was udp - but
nobody was listening...) to icmp echo and added the extension, that
the dom0 and the other guest ips are also pinged.
Because of the many different scenarios (three nested loops) over
packet sizes, two guests and different ip addresses, one run of this
test case takes now about 4.5 minutes.
