osage: MSBuild: define GVDLL to ensure correct storage-class attributes

An upcoming commit will change the storage-class attributes in
globals.h to be controlled only by the GVDLL symbol, not also by the
WIN32_DLL symbol.

Without this change, errors like this would occur:

osage.lib(osageinit.obj) : error LNK2001: unresolved external symbol _Ndim
