nixos/tests/docker: wait for docker service (#109418)

Browse Source 
Previously the Docker daemon was started by systemd socket activation.
Thus, the Docker test waited for the sockets.target unit.
But when the docker module was changed to start the Docker daemon at
boot instead of by socket activation, the test was left untouched.
With the Docker 20.10 update this lead to a timing issue, where the
docker command is run before the Docker daemon has started and hangs.

Fixes #109416
