ll_union_merge(): rename path_unused parameter

The "path" parameter to ll_union_merge() is named "path_unused", since
we don't ourselves use it. But we do pass it to ll_xdl_merge(), which
may look at it (it gets passed to ll_binary_merge(), which may pass it
to warning()). Let's rename it to correct this inaccuracy (both of the
other functions correctly do not call this "unused").

Note that we also pass drv_unused, but it truly is unused by the rest of
the stack (it only exists at all to provide a generic interface that
matches what ll_ext_merge() needs).
