Fix Windows builds 

This fixes a missing symbol error due to the weird way how
Windows maps the same, identical symbols using different addresses
in .dll and .exe.  Here specifically for

int luabridge::CFunc::vectorToArray<double, std::vector<double, std::allocator<double> > >(lua_State*)

which was added in 5e1a73a28c resulting in

gtk2_ardour/luainstance.cc error: explicit instantiation of 'static const void* luabridge::ClassInfo<T>::getStaticKey() [with T = std::vector<double>]' but no definition available [-fpermissive]
