selftests: mptcp: add last time actions tests

This patch adds a new helper chk_msk_info() to show the counters in mptcp_info of the given infos, and check that the timestamps move forward. Use it to show newly added last_data_sent, last_data_recv and last_ack_recv in mptcp_info in diag.sh. Signed-off-by: Geliang Tang <[email protected]>
