Subject: [PATCH] rootstate.c: Fix -Wmissing-braces compile warning

In Python 3.12 [1], ob_refcnt became part of an anonymous union
along with ob_refcnt_split, which is conditionally compiled in.
Instead of adding braces and implicitly assigning the former
ob_refcnt to the new field inside the union, just use a designated
initializer, just like how cpython itself does it with
_PyObject_HEAD_INIT.
