21f7373e76 Initial changes to support AArch64 
This is a work in progress:
- Syscall tables need work
- Only tested on real hardware using one of our test hosts

As a drive-by, this change also enables the open source version to function on
POWER.

Another side-effect of this change is that the default policies no longer
check for different host architectures at runtime. On x86_64, we do not need
to check for PPC or AArch64 specifice and vice versa.

6a1e4b881c Introduce config header to centralize CPU architecture checks 
This allows us to remove some uses of macros.

Related changes:
- Make it clear that we support hosting sandboxed binaries from 64-bit
  processes only. CPU architectures are x86-64 and POWER64 (little endian).
- Introduced CPU architecture macros, abstracting away compiler specifics

4da8f68aa8 Rework stacktrace mounttree logic 
The previous one was not quite correct in cases where the outside binary path
did not match the inside path. This should be fixed with this.

f29a5a81ed Print final FS mounts in sandboxee's chroot 
After all requested filesystem mounts are fully mounted under a sandboxee's virtual chroot, print a list of the outside paths and a list of the inside chroot paths that the outside paths are mapped to. This provides a valuable insight while debugging sandboxed binaries.
