selftests: mptcp: run mptcp_sockopt from a new netns
Not running it from a new netns causes issues if some MPTCP settings are modified, e.g. if MPTCP is disabled from the sysctl knob, if multiple addresses are available and added to the MPTCP path-manager, etc. In these cases, the created connection will not behave as expected, e.g. unable to create an MPTCP socket, more than one subflow is seen, etc. A new "sandbox" net namespace is now created and used to run mptcp_sockopt from this controlled environment.
