2851: Use uninterruptibleCancel in JobPool r=coot a=coot

JobPool is using bracket which requires that the resource finalizer is
uninterruptible.  Could this introduce a deadlock? I don't think so, only if
there already was a deadlock which forbid to deliver asynchronous exception.
This could happen either deadlock in FFI, or a tight loop which does not
allocate.

Both `async` library is using `uninterruptibleCancel` in `withAsync`
combinator, and `ouroboros-consensus` is using it as well in their more
sophisticated version of `ResourceRegistery`.

- job-pool: use uninterruptible handler in bracket
