devtools/gerrit: backport reviewiers column fix to 3.3.2

Gerrit 3.3.1 seems to have introduced a bug which makes the reviewers
column in the dashboard entry: https://bugs.chromium.org/p/gerrit/issues/detail?id=13899

This adds an override of gerrit.war to our Docker containers. The .war
is pulled over HTTP. It has been manually built by q3k from a source
checkout. The details on how this was done are in the WORKSPACE
http_file archive.

Once 3.3.3 lands we should get rid of it.
