dyngroups: Always run all tasks

Adding the `always` tag to the tasks in `dyngroups.yml` ensures that
hosts will get added to the appropriate groups dynamically, even when
running a subset of tasks by targeting specific tags.  Ansible will
always run tasks with this tag when a tag selection is passed to
`ansible-playbook`.
