[PATCH v2] msscript.ocx: Supply a stub ServiceProvider to InvokeEx in run_procedure.

I don't know what Windows supplies this object for (I tried all the SIDs in
Wine's headers and none pass except SID_GetCaller), but this does "match"
Windows behavior. More importantly, should an app request some service,
we can now see it in the FIXME and implement it accordingly.
