[PATCH 07/10] exec: Add support for AArch64 executables

[Sergey Bugaev]

This maps to EM_AARCH64.  Just like the x86_64 branch, we only compile
this code if CPU_TYPE_ARM64 is defined in Mach headers, to avoid
raising Mach version requirement on other architectures; and we
explicitly enable the branch when building for AArch64 itself, to get
a build error if CPU_TYPE_ARM64 is somehow not defined.
