unbound.inc should not add 127.0.0.0/8 in forward mode
Introduced in the commit , the local DNS servers are appended to unbound forward-zone. The function get_dns_servers() returns the parsed content of /etc/resolv.conf which also contains 127.0.0.1. This makes sense if one have a second DNS server running, with unbound running on a different port.
Maybe it makes sense to filter for the private net (127.0.0.0/8) if one want to use forwarding mode
