Subject: [PATCH] Bug 33962: Remove background job from process koc

The last occurrence of C4::BackgroundJob is in process_koc.pl that is used to upload a file.
Added by bug 2608 (15 years ago), I think it does not longer make sense as networks are faster, and we should not expect big koc files to be uploaded.
If there are complains we will move it to Koha::BackgroundJob.

Test plan:
Upload a koc file, enqueue the operations and confirm that everything is
working correctly
