fix issue3120 - don't truncate handles on 64-bit Windows.
This is still messy, realistically PC/_subprocess.c should never cast pointers
to python numbers and back at all.
I don't have a 64-bit windows build environment because microsoft apparently
thinks that should cost money. Time to watch the buildbots. It builds and
passes tests on 32-bit windows.
