    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.
