Fix Typo

Fixed Typo: Behing/Behind.

This fixes a confusing UX where a previously successful deployment's
healthy/unhealthy count would get updated if any allocations failed after
the deployment was already marked as successful.

client: handle 0.8 server network resources

Update hashicorp/go-msgpack/codec

Fixes https://github.com/hashicorp/nomad/issues/5587

When a nomad 0.9 client is handling an alloc generated by a nomad 0.8
server, we should check the alloc.TaskResources for networking details
rather than task.Resources.

We check alloc.TaskResources for networking for other tasks in the task
group [1], so it's a bit odd that we used the task.Resources struct
here.  TaskRunner also uses `alloc.TaskResources`[2].

The task.Resources struct in 0.8 was sparsly populated, resulting to
storing of 0 in port mapping env vars:

```
vagrant@nomad-server-01:~$ nomad version

vagrant@nomad-server-01:~$ nomad server members
