Apply same permissions to pmem-region alignments.
https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/1979257 created a padding of read-only pages between the end of the pmem region and padding up to the next multiple of 2MiB. However, on ARM systems, kvm_arch_prepare_memory_region does not permit read-only pages on a write-able memory region.
