Francesco Ruggeri 3c28d99fc6 selftest: net: add some traceroute tests
Added the following traceroute tests.

IPV6:
Verify that in this scenario

       ------------------------ N2
        |                    |
      ------              ------  N3  ----
      | R1 |              | R2 |------|H2|
      ------              ------      ----
        |                    |
       ------------------------ N1
                 |
                ----
                |H1|
                ----

where H1's default route goes through R1 and R1's default route goes
through R2 over N2, traceroute6 from H1 to H2 reports R2's address
on N2 and not N1.

IPV4:
Verify that traceroute from H1 to H2 shows 1.0.1.1 in this scenario

                   1.0.3.1/24
---- 1.0.1.3/24    1.0.1.1/24 ---- 1.0.2.1/24    1.0.2.4/24 ----
|H1|--------------------------|R1|--------------------------|H2|
----            N1            ----            N2            ----

where net.ipv4.icmp_errors_use_inbound_ifaddr is set on R1 and
1.0.3.1/24 and 1.0.1.1/24 are respectively R1's primary and secondary
address on N1.

v2: fixed some typos, and have bridge in R1 instead of R2 in IPV6 test.
