tools/python: remove broken xl binding

Various people say this binding doesn't compile or doesn't work. Remove
it for the benefit of xl feature development -- so that new features
won't need to worry about making this broken binding happy.

This isn't going to expose any user visible changes because that module
is not built by default.
