Never rescue jobs that return a timeout of -1

Fix a bug in the job rescuer in that jobs with a timeout of -1 (meaning
no timeout) should never be rescued, but they were being rescued.

Fixes #1287.

 ### Fixed
 
 - Fix `JobCancel` having no effect on running jobs when using a poll-only driver (e.g. `riverdatabasesql`). The `controlActionCancel` event was silently dropped in `fetchAndRunLoop`'s `queueControlCh` handler instead of being forwarded to `maybeCancelJob`. Note: this fix only works within a single process; cross-process cancels in poll-only setups must wait for the next poll cycle. [PR #1245](https://github.com/riverqueue/river/pull/1245).
+- Ensure jobs that return a custom timeout of -1 (no timeout) are never rescued. [PR #1288](https://github.com/riverqueue/river/pull/1288).
