Add EXPORT_SYMBOL() for the uf_find() and uf_union() functions to allow kernel modules, including the KUnit tests for the Union-Find data structure, to use these functions. This enhances the usability of the Union-Find implementation in a modular context, facilitating easier testing and integration.
