worker: Fix tracing instrumentation (rust-lang#11358)

For some reason only background jobs with the `#[instrumented]` annotation were receiving the `job.id` and `job.typ` fields from the parent span. This commit adjusts the `span` usage to not require the annotation and attach these fields for all background jobs.
