Matthieu Baerts f59549814a selftests: mptcp: userspace: validate v4-v6 subflows mix
commit 4656d72c1efa495a58ad6d8b073a60907073e4e6 upstream.

MPTCP protocol supports having subflows in both IPv4 and IPv6. In Linux,
it is possible to have that if the MPTCP socket has been created with
AF_INET6 family without the IPV6_V6ONLY option.

Here, a new IPv4 subflow is being added to the initial IPv6 connection,
then being removed using Netlink commands.
