From: Chengchang Tang <tangchengchang@huawei.com>

According to the programming guide, the rte_eal_init should be used pairs
with rte_eal_cleanup.

So, we should add the use of clean up to the hello world example to
encourage new users of DPDK to use it.

Fixes: af75078fece3 ("first public release")
