gnu: ocaml: Switch to ocaml 4.09 by default.

Bap and earley cannot be updated as they do not support 4.09 yet. Bap requires
the janestreet packages, which cannot be upgraded as no version supports
4.09 and 4.07 at the same time. Moreover, newer versions of the
janestreet packages have a different dependency graph, which will
require a whole new set of packages. We cannot simply use
package-with-ocaml4.07 on them.
