Remove pip and related dependencies from host

[traversaro]

Since https://github.com/conda-forge/idyntree-feedstock/pull/20/files the python bindings are installed with pure cmake, so we should have removed also the related dependencies.

This fixes the linter error in #100 (comment) .

@conda-forge-admin please rerender
