bug#69996: Broken OCaml packages (e.g. frama-c and binsec)

[pukkamustard]

As reported by Arnaud (off-list mail) some OCaml packages build fine but
seem to be broken.

Examples include `frama-c` and `binsec`:

```
guix shell frama-c -- frama-c
[kernel] Current source was: :0
  The full backtrace is:

```
guix shell binsec -- binsec -v

[Julien Lepiller]

At least for Frama-C, the issue is environment variables. It requires OCAMLPATH to work correctly. So this works:

guix shell frama-c ocaml -- frama-c

Even though the compiler is not needed.

It's another example of why we should propagate search paths, although we could also redefine the same search path in packages that need it ;)
