anubis: 1.21.3 -> 1.22.0
The new preact challenge uses go generate and depends on the
node_modules directory being available. To make things easier and more
closely to how upstream builds things, I removed the xess package and
added some, lets be honest to ourselves, hacks to build the new things
without breaking the FODs.
