Fix blackhole/reject routes.
Traditionally *BSD routing stack required to supply some interface data for blackhole/reject routes. This lead to varieties of hacks in routing daemons when inserting such routes. With the recent routeing stack changes, gateway sockaddr without RTF_GATEWAY started to be treated differently, purely as link identifier. This change broke net/bird, which installs blackhole routes with 127.0.0.1 gateway without RTF_GATEWAY flags. Fix this by automatically constructing necessary gateway data at rtsock level if RTF_REJECT/RTF_BLACKHOLE is set.
