Add LibreSSL test support

This takes advantage of zzak/ruby-openssl-docker@e26d90172

Since the build container has Ruby without stdlib openssl,
when building the gem to install locally we can't require openssl.

This means that the gemspec has to use static version constant.

We also removed bundler from development.
