The header size should be 24 bytes only, if we don't want to fuzz the
payload too.  Moreover, the default lambda parameter is decreased to
one, to not fuzz the header too heavily, and consequently increase too
much the time for the test to complete, due to exponential
retransmission timeout when packets are corrupted.
