tools headers UAPI: Sync files changed by new futex_waitv syscall

To pick the changes in these csets:

  f0e89eb4c15c0daa ("futex,x86: Wire up sys_futex_waitv()")
  f951ea88215ee779 ("futex: Implement sys_futex_waitv()")

That add support for this new syscall in tools such as 'perf trace'.

For instance, this is now possible:

  # perf trace -e futex_waitv
  ^C#
  # perf trace -v -e futex_waitv
  Using CPUID AuthenticAMD-25-21-0
  event qualifier tracepoint filter: (common_pid != 807333 && common_pid != 3564) && (id == 449)
  mmap size 528384B
  ^C#
  # perf trace -v -e futex* --max-events 10
  Using CPUID AuthenticAMD-25-21-0
  event qualifier tracepoint filter: (common_pid != 812168 && common_pid != 3564) && (id == 202 || id == 449)
  mmap size 528384B

  #

That is the filter expression attached to the raw_syscalls:sys_{enter,exit}
tracepoints.

  $ grep futex_waitv tools/perf/arch/x86/entry/syscalls/syscall_64.tbl

This addresses these perf build warnings:
