logind: ignore lid switch events for 30s after each suspend and 3min after startup
This is needed to give USB docking stations and suchlike time to settle, so that a display connected to an USB docking station can actually act as a lid swith inhibitor correctly. With this change we should have somewhat reliable docking station support in place.
