tools headers: Sync uapi/linux/prctl.h with the kernel source

tools headers: Sync uapi/linux/prctl.h with the kernel source

To pick up the changes in these csets:

  5ca243f6e3c30b97 ("prctl: add arch-agnostic prctl()s for indirect branch tracking")
  28621ec2d46c6adf ("rseq: Add prctl() to enable time slice extensions")

That don't introduced these new prctls:

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

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
       0.000 Isolated Servi/3474327 syscalls:sys_enter_prctl(option: SET_NAME, arg2: 0x7f23f13b7aee)

This addresses these perf build warnings:

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

Please see tools/include/uapi/README for further details.
