tools include UAPI: Sync linux/stat.h with the kernel sources

To get the changes in:

  2a82bb02941fb53d ("statx: stx_subvol")

To pick up this change and support it:

  $ tools/perf/trace/beauty/statx_mask.sh > before
  $ cp include/uapi/linux/stat.h tools/perf/trace/beauty/include/uapi/linux/stat.h
  $ tools/perf/trace/beauty/statx_mask.sh > after

Now we'll see it like we see these:
