Fix Windows build after UserIDResolver patch.

That patch added a function to HostInfo that returns an instance
of UserIDResolver, but this function was unimplemented on Windows,
leading to linker errors.  For now, just return a dummy implementation
that doesn't resolve user ids to get the build green.
