This commit updates the list of Node.js `fs` APIs to be patched because they haven't been updated for a long time. It adds `opendir,lutimes,writev`. For example, the `opendir` method was added to Node.js in version 12.12.0 in 2019, causing some of the APIs to potentially be always called within the `<root>` context. **Note:** There are missing unit tests for these changes because in unit tests, `fs` is patched by Bazel's Node.js rules and its `node_patches.cjs`. However, the APIs are successfully patched in the real production code and are called with the correct context. PR Close #54396
