Update config.h.win32.in for Newer Windows

Make use of if_indextoname() and if_nametoindex() when building against
Window Vista/Server 2008 or later, as these are provided by the system.

This is not turned on by default as we still want to support XP and
Server 2003-turn this on by changing _WIN32_WINNT to 0x600 or later prior
to compiling GLib.
