dune upgrade: include jbuild.inc fails

[avsm]

Continuing the dune upgrade on a duniverse, camomile also fails.

File "ocaml_modules/camomile/Camomile/charmaps/dune", line 22, characters 0-20:
22 | (include jbuild.inc)
     ^^^^^^^^^^^^^^^^^^^^
Error: File ocaml_modules/camomile/Camomile/charmaps/jbuild.inc doesn't exist.

(alias

 (action

(include jbuild.inc)

Looks like something changed regarding include semantics from jbuild -> dune

Oh... We do upgrade the included files, however we don't update the filename inside the (include ...) stanza :see_no_evil:
