deperecated bindings

[colin-gd]

Hi, when trying to install ocsigenserver and eliom I stumpled upon a compilation error. According to Vasilis Papavasileiou (from the ocsigen mailing list) the error could be that the ocaml-ssl binding still refer to OpenSSL bindings deprecated in version 1.1. In fact, reverting the version of libssl to 1.0 fixed the issue.

The error reported when compiling ocsigenserver :
