bug#25235: Wrapped python programs get native-inputs in PYTHONPATH

We cannot simply remove it: it is meant for packages that provide
standalone programs, such as ‘certbot’.  For these, it automatically
wraps bin/* and we don’t even have to have propagated inputs, which is
pretty cool.

However, you are right that native inputs shouldn’t be there.  Probably
we need to add some filtering in the ‘wrap’ phase?
