rpminspect trips up on some old networking functions in libgtop, which
are mentioned as deprecated in the Linux man pages.
inet_ntoa() only works on IPv4 addresses, whereas the newer inet_ntop()
works on both IPv4 and IPv6 addresses, so use inet_ntop() instead.
Similarly, use getaddrinfo() rather than gethostbyname(), and avoid
inet_addr() entirely.
