Refactor Couchbase 2.5 Docker setup and scripts

Updated Dockerfile to add libssl0.9.8, split some RUN commands, and improved permissions handling. Modified entrypoint.sh to use 'set -ex' for better debugging and switched to 'runsvdir -P /etc/service' for process management. Cleaned up docker-compose.example.yml by commenting out unused options. Updated run script to unset HOME before execution for improved environment consistency.
