[ci] [docker] Pin specific versions of OPAM CI dependencies.

Packages such as `menhir` or `elpi` are fragile w.r.t. updates, so
allowing a non-deterministic install in the Dockefile seems risky. We
have found trouble with Menhir in the past. We thus specify a concrete
version for all `CI_OPAM` packages.

cc: AbsInt/CompCert#234

We also add remove `hevea` from `apt` dependencies as it hasn't been
needed since coq#7466 and add `texlive-science` which is needed to build
the `source-doc` target due to the `textgreek` package being used.
