[Bug 1817065] [NEW] apt/trusty: Unset proxy variables in tests

[Julian Andres Klode]

Public bug reported:

[Impact]
apt autopkgtest on armhf fails in trusty, as it applies the no_proxy setting to the apt.conf defined proxy, which fails a test that requires using the proxy.

Cherry pick a fix to unset all proxy related variables that we've been
using in apt since 2015.

[Test case]
Make sure we don't fail with

W: Failed to fetch
http://localhost:8080/dists/unstable/main/source/Sources  400  Bad
Request [IP: ::1 8080]

in test-bug-717891-abolute-uris-for-proxies  on armhf

[Regression potential]
testsuite-only change, so regressions are restricted to more failing autopkgtests.
