  dpdk-hugepages.py had /dev/hugepages hardcoded as the mount point.
It may be desirable to setup hugepage directory at another path,
for example, when using hugepages of multiple sizes in different
directories or when granting different permissions to mount points.
Add --directory/-d option to the script.
