convertitem() raises SystemError when '#' is used without PY_SSIZE_T_CLEAN defined.
skipitem() should do it too.

I would rewrite this code in the form:

if (!(flags & FLAG_SIZE_T)) {
    ...
}
(void) va_arg(*p_va, Py_ssize_t *);

`convertitem()` raises `SystemError` when 'GH-' is used without `PY_SSIZE_T_CLEAN`.
This commit makes `skipitem()` raise it too.
(cherry picked from commit 4ebf4a6)
