Fix hostpython dependencies not installed for CythonRecipe

[DreamNik]

Then "setup.py" depends on some hostpython's package, it won't be installed when placed in hostpython_prerequisites.

This causes recipe to fail during invoke of "setup.py" on first and on second build.
The first build in that case won't produce cython files and second build will fail because of that.
