  This patch adds memarea perftest to malloc_perf_autotest.

The memarea perftest contains two part:
1) rte_memarea.heap: the memory source comes from invoking
rte_malloc_socket().
2) rte_memarea.libc: the memory source comes from invoking malloc().

Test platform: Kunpeng920
Test command: dpdk-test -a 0000:7d:00.3 -l 10-12

Note: The rte_malloc time includes obtaining memory from the system,
but rte_memarea time don't includes these (it uses pre-allocated
policy).
