Bug 32992: Move background_jobs_worker to misc/workers

On bug 32594 we are adding a new worker, dedicated to Elastic indexing.
We should have a common place for workers, and we agreed on misc/workers

To test:
1 - Apply patch
2 - reset_all in koha testing docker
3 - ps aux | grep background
4 - Confirm the workers are running, and running in the new directory
5 - Perform a batch item modification
6 - Ensure the job is processed by the worker
