ci: 336 runs on the one job that has qemu-arm, and its PASS line is demanded

336 declares `# requires: qemu-arm`, which no sharded runner has, so on a shard
it exits 0 without running a single row. Adding it to the loop and not to the
assertions below would have been that defect one layer in — the same shape the
comment above 332 already records. Both the PASS line and a row count are
demanded, because a fixture that stopped iterating still prints its PASS line.
