fstatat: extend tests and documentation
Document the fstatat behaviour leading to a ENOENT errno, and extend
tests to test the case where filename does not exist.

commit 521b4d6c4d5a7c84efd2742e0aac6311eaef005b
Author: Matteo Croce <teknoraver@meta.com>

fstat: add test and documentation for an edge case.
The fstatat behaviour when the target is a dangling symlink is different
if flags contains AT_SYMLINK_NOFOLLOW or not.
Add a test for this and document it.

commit 55e85c1e48c2aae71c0b5907fd22a3e9b978b6e8
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Fri Jul 18 17:03:04 2025 -0700
io/tst-stat.c: Use a temporary directory for symlink test
Call support_create_temp_directory to create a temporary directory for
symlink test, instead of a fixed file in the glibc source tree, to avoid
the race condition when there are more than one glibc tests running at the
same time with the same glibc source tree. This fixes BZ #33178.
