tests: avoid spurious failure in 'suffix3.tap'

* tests/suffix3.tap (foo.zoo): This C++ file fails to compile with
older g++ (3.4.4) on Cygwin 1.5.25 if we #include <iostream>.  Don't
do that, since it's not strictly required, and the "using namespace"
directive is already enough to ensure the file contents is valid C++
but invalid C.
