Minimal autobuilder environments don't always have working TCP, so we may need to skip TCP tests. Make sure we test the equivalent code paths via Unix sockets in those environments. One notable exception is test/fdpass.c, which uses TCP as a transport that is known not to be able to carry Unix fds; this needs to continue to use TCP.
