These patches from Geliang add support for the "last time" field in
MPTCP Info, and verify that the counters look valid.

Patch 1 adds these counters: last_data_sent, last_data_recv and
last_ack_recv. They are available in the MPTCP Info, so exposed via
getsockopt(MPTCP_INFO) and the Netlink Diag interface.

Patch 2 adds a test in diag.sh MPTCP selftest, to check that the
counters have moved by at least 250ms, after having waited twice that
time.
