Subject: [PATCH v2 3/4] perf augmented_raw_syscalls: Support arm64 raw syscalls

This patch adds support for arm64 raw syscall numbers so that we can use
it on arm64 platform.

After applied this patch, we need to specify macro -D__aarch64__ or
-D__x86_64__ in compilation option so Clang can use the corresponding
syscall numbers for arm64 or x86_64 respectively, other architectures
will report failure when compilation.
