Many of the upstream tests are really resource intensive, so if they fail while running in parallel on a given host, chances are decent they'll pass in serial, so we should fall back once before we give up.
See memcached/memcached#1220 (comment) (and preceding discussion) -- there's a really decent chance this fixes our failing builds on
arm32v5andriscv64(and we should re-enablearm32v6andarm32v7and give them a try again especially with this change, but that's a separate thing).
