Switch from OpenSSL to LibreSSL in Dockerfile

Many of the recent releases of Webdis have been to address major
vulnerabilities in OpenSSL. I'm hoping that LibreSSL will have fewer
CVEs, given its proactive approach and focus on security and code
clarity. The switch is easy given that the two libraries are
largely compatible with each other, meaning this will require no code
change in Webdis or its Hiredis dependency.
