Title: zmq: narrow condition to include TIPC in build/test

As TIPC transport for 0MQ will only work on post 3.8
Linux kernels where nonblocking connect was added,
we add AC_RUN test to check for this functionality.
Should the test fail, tipc is excluded from build/test.

The test tries to establish a connection to the TIPC
topology server (that's started immediately when the
module is installed). The test fails if we fail to create
an AF_TIPC socket (module not installed), or if the
nonblocking connection returns an error other than
the expected -EINPROGRESS.
