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

To pick the changes from:

  98d2b430 ("add unique mount ID")

That add STATX_MNT_ID_UNIQUE 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 differences:
    diff -u tools/include/uapi/linux/stat.h include/uapi/linux/stat.h
