dev-lang/ocaml: fix 4.11.2 src_prepare (missing patch)

Accidentally cleaned up in 9e83692 (got
confused by what I had/hadn't moved into patch tarballs, renamed accordingly
now to avoid that in future).

Once OCaml 4.09.0-r3 stabilisation is complete, we can cleanup all
the obsolete patches from files/ and then everything is a bit clearer.
