make docker_build_backend failed

[mielune]

Hi folks,

Thank you for this project, it seems to be a great tool for tech teams !

I would like to test it (and contribute ?) but trying the docker_build_backend it failed (from main branch) with:

error: failed to run custom build command for `openssl-sys v0.9.98`

Caused by:
  process didn't exit successfully: `/app/target/release/build/openssl-sys-5d78b13669bf8ca5/build-script-main` (exit status: 101)

  Could not find directory of OpenSSL installation, and this `-sys` crate cannot
  proceed without this knowledge. If OpenSSL is installed and this crate had
  trouble finding it,  you can set the `OPENSSL_DIR` environment variable for the
  compilation process.

  Make sure you also have the development packages of openssl installed.
  For example, `libssl-dev` on Ubuntu or `openssl-devel` on Fedora.

  If you're in a situation where you think the directory *should* be found
  automatically, please open a bug at https://github.com/sfackler/rust-openssl
  and include information about your system as well as this message.

Hey @mielune,
Build of the backend inside container is mainly fixed by this work. Could you test with that? :)

Good job, the backend build is working fine on your branch.
