golang: tests: Silence inspect deprecation warning

Every time tests are run under Python3 the following warnings are printed:

  golang/golang_test.py::test_func
    .../golang/golang_test.py:990: DeprecationWarning: inspect.getargspec() is deprecated since Python 3.0, use inspect.signature() or inspect.getfullargspec()
      assert inspect.formatargspec(*inspect.getargspec(MyClass.zzz)) == '(self, v, x=2, **kkkkwww)'

  golang/golang_test.py::test_func
    .../golang/golang_test.py:990: DeprecationWarning: `formatargspec` is deprecated since Python 3.5. Use `signature` and the `Signature` object directly
      assert inspect.formatargspec(*inspect.getargspec(MyClass.zzz)) == '(self, v, x=2, **kkkkwww)'

However since we are not going to drop Python2 support soon, and there is no
reffered "use-instead" functionality on Python2, let's simply silence the
warning for now.
