[SPARK-17127]Make unaligned access in unsafe available for AArch64
## # What changes were proposed in this pull request?
From the spark of version 2.0.0 , when MemoryMode.OFF_HEAP is set , whether
the architecture supports unaligned access or not is checked. If the check
doesn't pass, exception is raised.
We know that AArch64 also supports unaligned access , but now only i386,
x86, amd64, and X86_64 are included.
I think we should include aarch64 when performing the check.
## How was this patch tested?
