  1. pkg/sensors: add doc for hasMapsSetup 

    It can be confusing that only the per policy maps are configured here.
Noting that the per kprobe setup is done elsewhere.

  2. pkg/sensors: reduce memory footprint of unused override maps 

    Resize the override_tasks if needed to save memory, thus we are saving
~3MB of kernel memory by kprobe that are not using the override action.
