travis: fail fast if --with-marvin fails with nose (#3024)

* travis: fail fast if --with-marvin fails with nose

Install missing dependency pycrypto.
This fixes issue with recent Travis runs which gave incorrect results
around smoketests with simulator where each test run failed with an
error like "nosetests: error: no such option: --with-marvin".
