libpinmame: Fix Dip Switch bug in wpc/core.c

[diego-link-eggy]

From the code in wpc/core.c , it looks like the intent was for LIBPINMAME to use the VP Interface.

#if defined(VPINMAME) || defined(LIBPINMAME)  
#include "vpintf.h"

This PR adds the same define for core_getDip function further down in the same file

The code in win32com/Controller.cpp get_Dip and put_Dip functions also call to the VP Interface.

STDMETHODIMP CController::put_Dip(int nNo, int newVal)
{
	// TODO: Add your implementation code here. DONE
        vp_setDIP(nNo, newVal);
	return S_OK;
}

This change at least fixes the dipswitch reading on standalone branch of vpinball which would not read the
Controller.Dip()
when set .
