fuel-library: AArch64: nova: Backport NUMA support
This functionality was working as expected in Colorado, but the patch was silently discarded by mistake during the Newton rebase. JIRA: ARMBAND-90 Change-Id: Ibd31f68c823cbca6759b5c45d4005201b462b150 Signed-off-by: Alexandru Avadanii <Alexandru.Avadanii@enea.com>

++Subject: [PATCH] Adding hugepage and NUMA support check for aarch64
++
++Nova ignores aarch64 while verifying for hugepage and NUMA support.
++AARCH64 also supports hugepage and NUMA on the same libvirt versions as of x86.
++Hence adding this chek for aarch64 also.
