gnu: ocaml-llvm: Move to (gnu packages llvm).

Commit 8f710cc598fb675d267f49a82cffc197f03ad52c introduced a circular
dependency between ocaml.scm and llvm.scm by referring to 'llvm' from
the top level of ocaml.scm.  This fixes it.

* gnu/packages/ocaml.scm (make-ocaml-llvm, ocaml-llvm)
(ocaml-llvm-9, ocaml-llvm-10, ocaml-llvm-11): Move to...
* gnu/packages/llvm.scm: ... here.
