Expected Behavior

Compilation success.

Actual Behavior

Compilation error.

Reproduction

1. define a site whose name is a reserved Ocaml keyword, eg.,
   dune-project:

   (package
    (name my-package)
    (sites (lib include))
   

   dune:

   (generate_sites_module
    (module sites)
    (sites my-package))
   ...
   

2. dune build generates and tries to build the following Sites.ml:

   module Sites = struct
       let include = Dune_site.Private_.Helpers.site
         ~package:"my-package"
         ~section:Dune_section.Lib
         ~suffix:"include"
         ~encoded:(Sys.opaque_identity "%%DUNE_PLACEHOLDER:...%%")
   end

3. Compilation obviously fails with a syntax error.
