This patch adds ipv6 defragmentation tests to ip_defrag selftest,
to complement existing ipv4 tests.

This test creates a raw IPv4 socket, fragments a largish UDP
datagram and sends the fragments out of order.
Then repeats in a loop with different message and fragment lengths.
Then does the same with overlapping fragments (with overlapping
fragments the expectation is that the recv times out).
Tested:
root@<host># time ./ip_defrag.sh
ipv4 defrag
PASS
ipv4 defrag with overlaps
PASS
real 1m7.679s
user 0m0.628s
sys 0m2.242s
A similar test for IPv6 is to follow.
