Indeed they exist but only for ocaml-4.02, I hope doing new patches for
the current version was the right thing to do.

Regarding the test, I only disabled them if they don't exist.  I have
added comments to clarify that.  Regarding the versioning number
(113.33.xx in 2016 to 0.9.0 in 2017...), I have no idea what happened.

Here is the first patch, the others are following.

* gnu/packages/ocaml.scm (ocaml-sexplib0): New variable.
