parsers: use PyVarObject_HEAD_INIT

The macro changed slightly in Python 3, introducing curly brackets
that somehow confuse Clang into issuing a ton of compiler warnings.
Using PyVarObject_HEAD_INIT makes these go away.

It's worth noting that the code is identical: the 2nd argument to
PyVarObject_HEAD_INIT is assigned to the ob_size field and is
inserted immediately after "PyObject_HEAD_INIT(type)" is generated.
Compilers are weird.
