tools/ocaml/*/Makefile: generate paths.ml from configure

paths.ml contains various paths known to configure, and currently is generated
via a Makefile rule.  Simplify this and generate it through configure, similar
to how oxenstored.conf is generated from oxenstored.conf.in.

This will allow to reuse the generated file more easily with Dune.

No functional change.
