monitoring/grafana: Remove erroneous elements in hosts-overview Grafana dashboard

The hosts-overview Grafana dashboard json file contains a repeated element, making
it invalid JSON. Some JSON parsers handle this. However, this prevents Jsonnet
from parsing the dashboard, which prevents the deployment of this dashboard via
Jsonnet.
