configs.monitoring: exempt every mount of the download dataset from DiskAlmostFull
yellow mounts the same ZFS dataset (tank/download) as neoprism's
/var/download, which is covered by DownloadSpace*, so DiskAlmostFull
fired for it. Match the exemption on the device of neoprism's series
instead of host and mountpoint.
