Accepting request 671988 from home:frispete:python

By now, the cffi dependency is fullfilled by chance, but back than,
I managed a situation, where pyOpenSSL was installed, but dysfunctional,
because cffi was missing...

- add local-intersphinx-inventories.patch for generating the docs
  correctly
- add fetch-intersphinx-inventories.sh to fetch the inventories

- add missing python-cffi dependency
