tools: Move Makefile.arch from perf/config to tools/scripts
After this patch other directories can use this architecture detector without directly including it from perf's directory. Libbpf would utilize it to get proper $(ARCH) so it can receive correct uapi include directory. Tested-by: Naveen N.
