Adds out of the box SSL support w/ IO::Socket::SSL

The new Dockerfiles preinstalls IO::Socket::SSL with its dependencies to give
users out of the box SSL support. For slim builds we also keep the lib32z1-dev
libssl-dev packages so when people run `cpanm Net::SSLeay` and it can be
upgraded it won't cause issues.

It slightly increases the resulting image from 144MB to 197MB
