Restore missing win32service.pyd to Windows build

BleachBit 1.12 had this file, and it was removed later. WilliamBE reported
cleaning System - Update Installers froze his system, and this probably
explains it. That process calls win32serviceutil.QueryServiceStatus(), but
only if there are any uninstaller files, so users without uninstaller
files would not notice the problem.
