Fix gerrit plugins templates, it's failing with bazel node does not exist

See for example
https://gerrit-ci.gerritforge.com/job/plugin-its-phabricator-bazel-master/
please.

Follows up change 1a2990948aa9f656acec6ce47b1cc4f263179500
to do it for the other plugin templates.

Otherwise it will fail to build due to bazel no longer being defined as
a node in jenkins ci.
