Bug#958549: libnet-dns-lite-perl: autopkgtest requires direct internet connection

[Niko Tyni]

Package: libnet-dns-lite-perl
Version: 0.12-1
User: debian-perl at lists.debian.org
Usertags: autopkgtest

It looks like this package requires a real internet connection for its
autopkgtest checks. This is not guaranteed to work, and is currently
causing problems for src:perl testing migration because the resulting
test failure looks like a regression due to perl.

I understand ci.debian.net has recently added China based arm64 workers
which can only access the internet via proxy, exposing this issue.

Quoting Simon McVittie in https://lists.debian.org/debian-ci/2020/04/msg00001.html:

  Tests may access the internet, but only HTTP and HTTPS can be relied
  on, and those only if access via a proxy (according to the http_proxy etc.
  environment variables) is implemented.

Failing run:

   t/05mx.t ........... 
   ok 1 - use Net::DNS::Lite;
   not ok 2 - lookup google.com mx
   
   #   Failed test 'lookup google.com mx'
