bug#72547: [PATCH 1/9] tests: Check TCP_NODELAY for non-zero instead of 1.

POSIX does not explicitly say that stored value using setsockopt will be
returned by getsockopt.  At least for TCP_NODELAY on Darwin they do
differ.  Darwin returns internal define TF_NODELAY (4) instead of 1 the
test expected.  Since for boolean flags "non-zero is true", rewrite the
test to check just that.

* test-suite/tests/00-socket.test ("setsockopt AF_INET")
["IPPROTO_TCP TCP_NODELAY"]: Check for non-zero value from getsockopt.
