Fix dashboard filter for Syslog dashboard

[mr-tri]

Proposed commit message

The link panel on the dashboard "[Logs System] Syslog dashboard" from the System integration is a bit broken.
If you click through the dashboards from left to right, you will have two filters on data_stream.dataset, one for system.syslog and one for system.auth, which will return no results and thus break the dashboard. To replicate, just open the dashboard and click on "Sudo commands". This is due to the missing useCurrentFilters:false link option, I added those to all dashboards containing the panel.
