wheels: declare 'cuda-pathfinder' dependency for libcudf

[jameslamb]

Description

Follow-up to #23414

Contributes to rapidsai/build-planning#307

libcudf wheels use cuda-pathfinder:

cudf/python/libcudf/libcudf/load.py

Lines 40 to 43 in ea199db

	from cuda.pathfinder import load_nvidia_dynamic_lib
	load_nvidia_dynamic_lib("nvJitLink")
	load_nvidia_dynamic_lib("nvrtc")

But don't explicitly declare a dependency on it. This fixes that.

I'm going to admin merge. The single CI failure is unrelated to this change and it is being fixed in #23883. No need to rerun CI here just for that.
