selftests: mptcp: support MPTCP_PM_CMD_SUBFLOW_CREATE
This change updates the "pm_nl_ctl" testing sample with a "csf"
(create subflow) option to support the newly added netlink interface
command MPTCP_PM_CMD_SUBFLOW_CREATE over the chosen MPTCP connection.
E.g. ./pm_nl_ctl csf lip 10.0.2.1 lid 23 rip 10.0.2.2 rport 56789
token 823274047
