Say what Varaverk itself is using on the System card

The card described the machine and said nothing about the thing whose dashboard
it is. Cache size matters most: VV_CACHE_ROOT is under /tmp, which on Unraid is
RAM, so it is shown against the rootfs percentage it counts against. Jobs are
locks with a live process — four lock files were sitting there and one job was
actually running.
