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



To pick up the changes in these csets:

  8cdc4d27 ("mm/huge_memory: respect MADV_COLLAPSE with PR_THP_DISABLE_EXCEPT_ADVISED")
  9dc21bbd ("prctl: extend PR_SET_THP_DISABLE to optionally exclude VM_HUGEPAGE")

That don't introduce anything of interest for the tools/, just
addressing 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.
