tools headers: Sync uapi/linux/prctl.h with the kernel source
To pick up the changes in these csets:
8cdc4d27019356b0 ("mm/huge_memory: respect MADV_COLLAPSE with PR_THP_DISABLE_EXCEPT_ADVISED")
9dc21bbd62edeae6 ("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.
