Clarify `kubelet_dockershim_nodocker` error message
Clarify `kubelet_dockershim_nodocker` error message

Clarify the error message returned when trying to use the docker runtime
on a Kubelet that was compiled without Docker.

We removed the "w/" and "w/o", which can be confusing abbreviations, and
also add slightly more detail on the actual error.
