python-pyzmq: bump to version 16.0.2

python-pyzmq: bump to version 16.0.2

Updated the zmq version detection patch to apply cleanly on 16.0.2.

Added patch #2 to replace compile_and_run with compile_and_forget in the setup
code: this function is only used to check for the availability of "sys/un.h" and
we only need to compile the test code to make sure of that. This fixes the
cross-compilation.
