Comment 4 for bug 1825744

Not sure if it warrants another bug report, so here's yet another patch that basically cleans up after the previous one plus rectifies some other broken links on the same page about autopkgtest.

1. The online version of running_test is the only one referenced on the page now, thus the part in the parentheses got superfluous.

2. The reference name running_tests_local is misleading now after the previous patch made it non-local, so I've got ridden of the _local part in the name.

3. For DEP8, the link to the raw blob replaced with the link to the rendered document.

4. For projects that migrated to Git, the dead links to https://bazaar.launchpad.net replaced with the current ones on https://git.launchpad.net
