Missing requirements in build

[lowks]

It might be a package issue, but when you run the command it results in this:

Running setup.py install for cryptography
    c/_cffi_backend.c:15:17: fatal error: ffi.h: No such file or directory
     #include <ffi.h>
                     ^
    compilation terminated.

This can be fixed by adding `libffi-dev` in the `apt-get install` command

Great. Could you please update the PyPi package? Currently ansible-test there is arguably broken.
