If the libuv operations invoked by `readdir`/`opendir` return
`uv_dirent_t` values where the `type` is `UV_DIRENT_UNKNOWN` then a
further `lstat` is issued to fully construct the `Dirent` values. In the
recursive versions of these functions, the `path` parameter was
incorrectly assumed to be the path to the entry when it should be the
path to the directory containing the entry.
Fixes#49499.
