tools headers uapi: Sync linux/stat.h with the kernel sources

To pick the changes from:

  825cf20 ("statx: add direct I/O alignment information")

That add a constant that was manually added to tools/perf/trace/beauty/statx.c,
at some point this should move to the shell based automated way.

This silences this perf build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/stat.h' differs from latest version at 'include/uapi/linux/stat.h'
  diff -u tools/include/uapi/linux/stat.h include/uapi/linux/stat.h
