Running DPDK 20.02-rc3 and attempting to use the MLX5 PMD as a non-root

Ended up with two answers:
1) Manually clean out /dev/hugepages. Often encountered root owned
files left over from previous test runs, causing memory allocation
failures when DPDK couldn't use the name it wanted (rtemap_*).
2) Needed to manually add special permissions to dpdk-testpmd (thanks
Shahaf):
# setcap cap_net_raw,cap_net_admin,cap_ipc_lock+eip
