Change default SCTP conn NULL->127.0.0.1 to localhost->localhost
"127.0.0.1" is changed to "localhost" to let local NSS decide whether to
use IPv4 or IPv6. In newish systems, IPv6 ::1 will be selected since
IPv6 takes precedence over IPv4.
Similarly, the default source addr needs to be changed from NULL to "localhost"
since for some yet unknwon reason, getaddrinfo(AF_UNSPEC, NULL) returns
first IPv4 "0.0.0.0" and later "::", which is inconsistent with
getaddrinfo("localhost") result, resulting in src=IPv4(0.0.0.0) and
dst=IPv6(::1), which is incompatible and will fail. In any case, since
the default remote address is a local one and it's the client side,
there's no real logical change since the kernel would anyway should have
taken a local address anyway.
