Move containerd.service from Requires= to Wants=

Per the systemd.unit documentation:

> If this unit gets activated, the units listed will be activated as well. If one of the other units fails to activate, and an ordering dependency After= on the failing unit is set, this unit will not be started. Besides, with or without specifying After=, this unit will be stopped if one of the other units is explicitly stopped.
>
> Often, it is a better choice to use Wants= instead of Requires= in order to achieve a system that is more robust when dealing with failing services.

This should also be generally "safe" given we added `--containerd=/run/containerd/containerd.sock` to the flags we pass to `dockerd`.
