This commit fixes error 'time="2020-10-16T…" level=error msg="Handler for POST
/v1.40/containers/…/start returned error: failed to start shim: exec:
\"containerd-shim\": executable file not found in $PATH: unknown"'.
* gnu/services/docker.scm
(containerd-shepherd-service): Add "containerd-shim" to PATH.
The userland proxy option does not properly disable the userland proxy when
set to false. Docker defaults to enabling the userland proxy if the option is
unset on the command line.
* gnu/services/docker.scm (docker-shepherd-service): Properly handle the
'enable-proxy?' option.
