Fix arm64 jobs on stable/xena

This is a combination of 2 commits:

=====================

Make arm jobs voting (but not the pipeline)

Make the non-voting pipeline indicate failure when any of the jobs
fail.

Previously zuul would report "Build succeeded (ARM64 pipeline)."
even when individual job(s) had failed. Now zuul will report
"Build failed (ARM64 pipeline)." but the pipeline still does
vote on the patchset.
