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

[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 ;)
