Because the host and guest share the same IP address with passt/pasta, it's not possible for the guest to directly address the host. Therefore we allow packets from the guest going to a special "NAT to host" address to be redirected to the host, appearing there as though they have both source and destination address of loopback. Currently that special address is always the address of the default gateway (or none). That can be a problem if we want that gateway to be addressable by the guest. Therefore, allow the special "NAT to host" address to be overridden on the command line with a new --map-host-loopback option. In order to exercise and test it, update the passt_in_ns and perf tests to use this option and give different mapping addresses for the two layers of the environment.
