fix: Sensor to apply exclude pattern for rootfs enumeration

[iximiuz]

Mounting a huge folder from the host filesystem can make sensor (almost?) stuck. Most of the time, you'd probably want the host mounts excluded from the minified image, however StartMonitor.Excludes wouldn't really help solving the slowness of the sensor's startup logic caused by such mounts. Hence, the fix.
