fix output of getaddrinfo in networking and streams documentation for v0.5.

Hi @musm! Thanks for this - I see this is just an example, and not a doctest. Do you think you could convert it to a doctest (is this a reasonable thing to do, @tkelman?) so that if the output syntax changes in the future, it'll be easier to catch?

The output looks like it might depend on your location. I get

julia> getaddrinfo("google.com")
ip"216.58.192.14"

[musm]

That's expected it depends on the dns server it pings. The syntax more importantly was wrong.

@kshyatt How do I convert to a doctest?

Hmm, if the output is going to change depending on where the docs are built it's probably not worth the effort. Nevermind! For next time, check out http://docs.julialang.org/en/latest/manual/documentation/
