Some errors occurs when shutdown or reboot on ARM

RancherOS Version: (ros os version)
All

We can see these logs on ARM:

$ reboot
...
...
 reboot:error: EOF
�.Error grabbing logs: function not implemented
reboot:error: EOF

It seems that our aarch64 system-docker doesn't support system-docker logs -f <container>
I can get these logs if I add -f:
error from daemon in stream: Error grabbing logs: function not implemented

I tried aarch64 docker 17.09+, it works fine with logs -f.
We have no plan to upgrade system-docker, now it's based on 17.06.

We have two choices:

1. Give system-docker a patch to support this feature
2. Force reboot on the arm64 platform, we will not use system-docker logs -f to check the containers' logs.

Finally, I patch our system-docker.
The system-docker 17.06-ros5 can support logs -f.
