ansible venv --system-site-packages causes conflicts

[Pas]

On ubuntu 16.10 yakkety (and probably on 16.04 xenial, where python-cffi-backend is 1.5.2) and using current master ( 42aaff7c5351e2520fcf5efc373041757519682a ) bootstrap installs python-cffi-backend distrib package, but then tries to install python package cryptography which somehow depends on python-cffi 1.9.

And then things inside the venv find the cffi from outside and produce an AssertionError version mismatch.

Editing ./scripts/bootstrap-ansible.sh works around this.

Could you provide the code in question by a patch or here?

Avoiding duplication of work seems smarter :)
