[TrigP1Test] Update timeout test error exclusion patterns following AvalancheSchedulerSvc stall message change
The timeout test is meant to test error handling on timeout, therefore it must be not flagged as failed when the error handling works correctly. Update the error exclusion patterns to avoid flagging correct AvalancheSchedulerSvc error messages as bad. This is following the change of these messages in gaudi/Gaudi!1339 (merged)
Fixes ATR-25961
