tools headers UAPI: Sync powerpc syscall table file changed by new futex_waitv syscall
To pick the changes in this cset:
  a0eb2da92b715d0c ("futex: Wireup futex_waitv syscall")
That add support for this new syscall in tools such as 'perf trace'.
For instance, this is now possible (adapted from the x86_64 test output):
  # perf trace -e futex_waitv
  ^C#
  # perf trace -v -e futex_waitv
  event qualifier tracepoint filter: (common_pid != 807333 && common_pid != 3564) && (id == 449)
  ^C#
  # perf trace -v -e futex* --max-events 10
  event qualifier tracepoint filter: (common_pid != 812168 && common_pid != 3564) && (id == 221 || id == 449)

This addresses this perf build warnings:
