tools arch x86 uapi: Synch asm/unistd.h with the kernel sources



To pick up the change in:

  700d3a5a ("x86/syscalls: Revert "x86/syscalls: Make __X32_SYSCALL_BIT be unsigned long"")

That doesn't trigger any changes in tooling and silences this perf build
warning:

  Warning: Kernel ABI header at 'tools/arch/x86/include/uapi/asm/unistd.h' differs from latest version at 'arch/x86/include/uapi/asm/unistd.h'
