Bug#867361: sitesummary: Fix autopkgtest to work in environments with http_proxy set

Dear maintainers,

Thanks for the work on improving the autopkgtest for sitesummary in recent
uploads.

In Ubuntu, sitesummary has been stuck at version 0.1.21 because this is the
last version of the package with an autopkgtest that didn't confirm the
results on disk; and the autopkgtest does not actually correctly test
sitesummary in an Ubuntu environment because http_proxy is set on our test
runners and so the test case is talking to a squid proxy instead of to the
local apache.

I have just uploaded the attached patch to Ubuntu, which should make the
autopkgtest work in the face of http_proxy (results will soon be visible at
http://autopkgtest.ubuntu.com/packages/s/sitesummary/artful/amd64).

Please consider including the patch in Debian as well.

Thanks,
