Re-opening so we can confirm that the flakiness gets fixed after the change is deployed.

Edit: The change from CL 129098 is deployed now.

dashboard: bump plan9-386-v5 image to v6 
plan9-386-v6 is a new plan9-386 image built with the change
done in CL 129098.

I tested it with cmd/debugnewvm on latest Go master commit,
and all stdlib tests passed, including TestVariousDeadlines.
(cmd/... tests didn't finish in time before cmd/debugnewvm
timed out.) Running it 3 more times, there was still one
TestVariousDeadlines failure and 2 successes, so we'll have
to keep watching it.

Updates golang/go#26945.
