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.

BTW, we don't need to export these functions until the time a kernel
module starts to use it. That is the usual rule.
