resolved: simplify detection of packets from the loopback device
We can simplify our code quite a bit if we explicitly check for the ifindex being 1 on Linux as a loopback check. Apparently, this is hardcoded on Linux on the kernel, and effectively exported to userspace via rtnl and such, hence we should be able to rely on it.
