Enable running of contrib/netbsd-tests/lib/libc/net/getaddrinfo without
modifications to the test program itself. However, create our own version
of expected results files. They are produced from the NetBSD files, with
the following list of changes:
o AF_INET6 value is different, hence: s/family 24/family 28/.
o SCTP result (socktype 5 protocol 132) needs to be added to many queries
results.
o NetBSD libc stores multiple results first by protocol, then by address
family. FreeBSD first sorts on address family, then on protocol. Some results need to be reordered.
o Error strings needs to be fixed:
s/hostname nor servname provided, or not known/Name does not resolve/ s/ai_family not supported/Address family not recognized/ s/servname not supported for ai_socktype/\ Service was not recognized for socket type/.
