Add missing line continuation characters

Add the line continuation characters missing from the recent ingress
lines which resulted in this error:

  + --set etcd.ingress.enableVirtualHosts=true
  /w/workspace/periodic-software-upgrade-test-bbsim@tmp/durable-9565aa33/script.sh: line 3: --set: command not found

Also include an extra change in jjb to trigger jenkins job in vars/.
