Bug#1033734: munin-plugins-core: nginx_*: example configuration does not work with ipv6 localhost

[Helmut Grohne]

Package: munin-plugins-core
Version: 2.0.67-3
Tags: patch

Hi,

I noticed that the example configuration included in the nginx_* plugins
does not work. Nowadays, localhost tends to resolve to ::1 and with the
example configuration, this yields an error. Thus, it would be good to
also listen on the ipv6 loopback to make it work. I'm attaching a patch.
