Newer selinux base policies now split out 'map' actions, as well as
adding more explicit checks for hugetlbfs objects. Where previously these
weren't required, recent changes have flagged the allocation of hugepages
and subsequent clearing. This means that the hugepage storage information
for the DPDK .rte_config, and clearing actions copying from /dev/zero will
trigger selinux denials.
This commit allows openvswitch to have more permissions for the hugetlbfs
allocation and use.

NOTE: I seem to have lost the system with the logs that were used to
generate this policy. If needed, I can ask to get access again and
recreate the scenarios.
