[Libguestfs] [PATCH] generator: Add some arguments to ocamlc in generator/Makefile.am to silence some warnings

[Tage Johansson]

From: Tage Johansson <frans.tage at gmail.com>

When running make with OCaml 5.0.0, the following warnings are sometimes
shown:

```
OCaml's lib directory layout changed in 5.0. The unix subdirectory has been
automatically added to the search path, but you should add -I +unix to the
command-line to silence this alert (e.g. by adding unix to the list of
libraries in your dune file, or adding use_unix to your _tags file for
ocamlbuild, or using -package unix for ocamlfind).
```

This commit adds the arguments `-I +unix -I +str` to the invocation of
ocamlc in generator/Makefile.am, which silences the warnings.
