tools: Move x86 syscall number fallbacks to .../uapi/

Move unistd_{32,64}.h from x86/include/asm to x86/include/uapi/asm so that tools/selftests that install kernel headers, e.g. KVM selftests, can include non-uapi tools headers, e.g. to get 'struct list_head', without effectively overriding the installed non-tool uapi headers. Swapping KVM's search order, e.g. to search the kernel headers before tool headers, is not a viable option as doing results in linux/type.h and other core headers getting pulled from the kernel headers, which do not have the kernel-internal typedefs that are used through tools, including many files outside of selftests/kvm's control. Prior to commit cec07f5 ("perf tools: Move syscall number fallbacks from perf-sys.h to tools/arch/x86/include/asm/"), the handcoded numbers were actual fallbacks, i.e. overriding unistd_{32,64}.h from the kernel headers was unintentional.
