anubis: split xess derivation into a separate package

Unfortunately, because the Xess file needs to be pre-processed and
consumed by the final derivation, it couldn't be overridden if it was
written in-line. This commit splits it into a separate `anubis-xess`
package that can be overridden/overlayed.

This also adds myself as a maintainer for Anubis, and removes the
`nix-update-script` call, since it was never necessary (because Anubis
is hosted on GitHub), stopped working after e049c438a9,
and it certainly won't work now. It also corrects the homepage URL.
