[PATCH net-next v2 6/8] selftests: traceroute: Reword comment

Both of the addresses are configured as primary addresses, but the
kernel is expected to choose 10.0.1.1/24 as the source IP of the ICMP
error message since it is on the same subnet as the destination IP of
the message (10.0.1.3/24). Reword the comment to reflect that.
