tools headers UAPI: Sync linux/prctl.h with the kernel sources to pick FUTEX knob

To pick the changes in:

  63e8595 ("futex: Allow to make the private hash immutable")
  80367ad ("futex: Add basic infrastructure for local task local hash")

That adds a FUTEX knob:

  $ tools/perf/trace/beauty/prctl_option.sh > before
  $ cp include/uapi/linux/prctl.h tools/perf/trace/beauty/include/uapi/linux/prctl.h
  $ tools/perf/trace/beauty/prctl_option.sh > after
  $ diff -u before after

   };
   static const char *prctl_set_mm_options[] = {
   	[1] = "START_CODE",

That now will be used to decode the syscall option and also to compose
filters, for instance:

  [root@five ~]# perf trace -e syscalls:sys_enter_prctl --filter option==SET_NAME

This addresses this perf build warning:

  Warning: Kernel ABI header differences:
    diff -u tools/perf/trace/beauty/include/uapi/linux/prctl.h include/uapi/linux/prctl.h
