fdpass test: assert that TCP connections don't say they can pass fds

Browse source 
As well as slightly increasing our test coverage, this ensures
that at least one test-case in this test is not skipped, working
around CMake's lack of support for the Automake-style exit code
produced by GTest executables (they exit 77 if everything was skipped).
