Bug#818460: tests fail during the build without network access

Package: src: ruby-http
Version: 1.0.2-2
Severity: serious
Tags: sid stretch patch
Some tests fail during the build without network access, seen at
https://launchpad.net/ubuntu/+source/ruby-http/1.0.2-2/+build/9343579

Patch to just disable these:
https://patches.ubuntu.com/r/ruby-http/ruby-http_1.0.2-2ubuntu2.patch

Maybe there is a better way to detect missing network access and then only 
disable these in this case.
