qa/suites/upgrade/*-x: ignore telemetry re-opt-in nudges

Cover warnings like

  [WRN] Health check failed: Telemetry requires re-opt-in (TELEMETRY_CHANGED)" in cluster log
  [WRN] telemetry module includes new collections; please re-opt-in to new collections with `ceph telemetry on`" in cluster log

Re-opt-in can happen in a respective workunit
(test_telemetry_quincy_x.sh or test_telemetry_reef_x.sh), but it gets
run only at the very end after both "workload" and "upgrade-sequence"
complete.  Over an hour passes in the interim:

  2024-12-08T00:06:31.197 INFO:teuthology.task.print:**** done end upgrade, wait...
  ...
  2024-12-08T01:28:38.588 INFO:tasks.workunit:Running workunit test_telemetry_reef_x.sh...

The existing list is now duplicated in 0-start.yaml, so replace it
entirely.
