cuda module: fully buy into new modules API

In commit 3340284805 the new ModuleObject
API got further updated to hide self.interpreter; at the time, the CUDA
module got transferred over to the wrapper which does provide it.

But it works fine without self.interpreter, so let's just use the best
base class.
