What are we going to do about testing this?

We should add libjson-c to some build containers.  We need to annotate #
Xen < 4.21 in the existing containers so we can drop it in due course.

Also, for a container we don't intend to backport to stable trees, we
should have libjson-c only and no yajl.  Probably best to do this in the
Alpine update which is long overdue.
