[jumbo] Windows build fix related to INITGUID

Generating GUID objects in a binary requires careful juggling
of includes and the define INITGUID (or the header <Initguid.h>).

Jumbo builds are not that careful so the simplest/best solution
is to remove the file doing INITGUID from jumbo compilation.
This manifested itself in jumbo fyi builders building
catalog_viewer_service.exe.
