zeromq: security bump to version 4.0.5

Fixes:
CVE-2014-7202 - stream_engine.cpp in libzmq (aka ZeroMQ/C++)) 4.0.5
before 4.0.5 allows man-in-the-middle attackers to conduct downgrade
attacks via a crafted connection request.
CVE-2014-7203 - libzmq (aka ZeroMQ/C++) 4.0.x before 4.0.5 does not
ensure that nonces are unique, which allows man-in-the-middle attackers
to conduct replay attacks via unspecified vectors.
