Aaron Tomlin 93e257938a tools/workqueue/wq_dump.py: Support backward compatibility for wq->attrs rename 
Commit 464e454e1c ("workqueue: rename wq->unbound_attrs to wq->attrs")
renamed wq->unbound_attrs to wq->attrs. When running wq_dump.py against
older running kernels or vmcores where struct workqueue_struct still
contains unbound_attrs, drgn raises an AttributeError.

Add a wq_attrs() helper to allow wq_dump.py to inspect both older and newer
kernel versions seamlessly.

Fixes: 464e454e1c ("workqueue: rename wq->unbound_attrs to wq->attrs")
