Gavin Hu b13a21890a ticketlock: use new API to reduce contention on aarch64 
While using ticket lock, cores repeatedly poll the lock variable.
This is replaced by rte_wait_until_equal API.

Running ticketlock_autotest on ThunderX2, Ampere eMAG80, and Arm N1SDP[1],
there were variances between runs, but no notable performance gain or
degradation were seen with and without this patch.
