Subject: [PATCH] kernel/numa: sleep 2s in test01 for waiting numastat updating

Without this patch always get the below error with kernel 4.6.0:
"ltpapicmd.c:193: Test #1: NUMA hit and localnode increase in node0 is
less than expected"

numastat's "local_node" might take some to update even though we malloc
the local memory for each node.

So this patch in targets to sleep for 2 seconds until "local_node" get
updated.
