python: Fix generated virInterface method names

A mistake in the generator was causing virInterface methods to be generated
with unpredicatable names ('ceUndefine', instead of just 'undefine'). This
fixes the method names to match existing convention.

Does anyone care if we are breaking API compat? My guess is that no one is
using the python interface bindings yet.
