On Windows, `long` is a signed 32-bit integer so it can't represent 0xffff_ffff without overflow. Windows exit codes are unsigned 32-bit integers, so if a child process exits with `-1`, it will be represented as 0xffff_ffff. Also fix a number of other possible cases where `_Py_HandleSystemExit` could return with an exception set, leading to a `SystemError` (or fatal error in debug builds) later on during shutdown.
