updates travis env (#851)
Browse files Browse the repository at this point in the history 
* this PR updates travis env

After last changes in `ocaml-ci-scripts`, a default version
of `opam` is `2.0`, that breaks our builds.
The simpliest fix is just to set an environment variable
`OPAM_VERSION=1.2.2`.

Also we can add theirs scripts directly to `bap`, like it
was some time ago, but I still suggest to do it only when
there wan't be any easy way to fix some issue from thier
side.

* added one more env var

* cleaned up

* returned an old version of ci-scripts
