add support for aarch64 to dwarfdump (#445)

llvm-dwarfdump prints
elf64-littleaarch64

We probably need more logic to differentiate between big endian (less
common) vs little endian (more common), but at least this allows us to
use ./scripts/dwarfdump on aarch64 targets now.

I probably should have added this to #318 / #317.
