[bug#38635] [WIP PATCH] Add why3 and frama-c

[Julien Lepiller]

Hi Guix!

Since there was some interest very recently, I took another look at my
incomplete why3 and frama-c packages. I updated them and polished them
a little. I encourage formal-method guixers to test these patches,
especially if you are a user of why3 or frama-c, because I'm not sure
how these tools are supposed to be working.

Note that I didn't include ide support in why3 because this adds ~1GiB
to the closure of the program. A good thing could be to separate the
why3 library (not required when using why3) from the main package, in a
separate output.

For some reason, frama-c doesn't work directly, it needs to be in an
environment where its dependencies are present, hence the propagation.
However, it's failing at runtime:

$ guix environment --ad-hoc frama-c ocaml ocaml-findlib
[env]$ frama-c --help
