[advpack] Implement RegisterOCX and stub out DelNodeRunDLL32

[Matthew Mastracci]

This patch helps the IE6 installer get past the DLL registration stage. 
  The DelNodeRunDLL32 function is stubbed out, but RegisterOCX will 
correctly register a COM DLL by calling its DllRegisterServer function.

ChangeLog:

* dlls/advpack/advpack.c

Matthew Mastracci 
     Implement RegisterOCX
     Stub for DelNodeRunDLL32
