Adding fake netlink socket implementation to support OpenSSH's sshd
- Support faked only for netlink_family NETLINK_ROUTE's RTM_GETADDR messages sent by getaddrinfo(3) using sendto(2)
- Hardcorded response(sent via sys_recvmsg) sends only the IPv4 address "127.0.0.1"
- Placeholders added to report as missing all netlink functionality not covered by above points
