Public bug reported:

[Impact]
The host capabilities for arm64 NUMA systems are incomplete - one effect of which is that nova is unable to make use of hugetlbfs for backing VMs with huge pages.

[Test Case]
Examine the output of 'virsh capabilities' on an arm64 NUMA system. The topology section for all but the first node are currently inaccurate and lacks page size entries. Sample output from a 2-node NUMA system is attached, both pre and post fix.

[Regression Risk]
Risk is minimized by the fact that this change is just enabling the same code for arm64 that is already enabled for the other NUMA-enabled Ubuntu architectures.
