Again, this seems to have been an artifact of porting the package
definitions from an old patch series. Sorry for the sloppyness.

ocaml-crowbar no longer has tests that rely on xmldiff. I've enabled the
tests and it just works.

A general note on another OCaml dependency: ocaml-calendar seems to be
unmaintained
(https://discuss.ocaml.org/t/calendarlib-looking-for-a-new-maintainer/3965)
and some fixes are included in an unreleased Git branch
(https://github.com/ocaml-community/calendar/tree/3.x). No action
required from Guix side at the moment, just worth keeping in mind.

Thanks for your review! Will send in V2 shortly.
