r/unifi: Switching to custom container image

The _linuxserver.io_ image for UniFi Network is deprecated.  It sucked
anyway.  I've created a simple image based on Debian that installs the
_unifi_ package from the upstream apt repository.  This image doesn't
require running anything as _root_, so it doesn't need a user namespace.
