iphlpapi: Add a stub for getInterfacePhysicalByName in case configure found no way to determine interface data

[André Hentschel]

I just had this case with Haiku, i know it's Haiku, but when there's one there are others too.
Further this way it seems cleaner. We do such things often in iphlpapi anyway.
