Fix Python 3.5 sizeof(PyGC_Head) for UBSan
...by again using 'long double' instead of 'double' to "force worst-case

failures like
> workdir/UnpackedTarball/python3/Modules/_ctypes/_ctypes.c:2923:10: runtime error: member access within misaligned address 0x6110007af498 for type 'CDataObject' (aka 'struct tagCDataObject'), which requires 16 byte alignment
