Create a Krill DEB package via GH actions:

- Assumes that the target system has ca-certificates installed already.
  - Vendor OpenSSL to support Ubuntu 16.04 which only has OpenSSL 1.0.0.
  - Use an Ubuntu 16.04 compatible version of libgcc1 (don't use cargo-deb $auto
    depends as the GH 16.04 runner has a much newer libgcc1 package than stock
    Ubuntu 16.04).
  - Use GH caching to avoid repeat compilation of unchanging cargo deb and krill
    dependencies.
  - Sanity check the created DEB in targeted O/S versions.
