Update MIB directory configuration for embedded files

- Update config.exs to point to /app/priv/mibs in production
- Update dev.exs to include priv/mibs root for standard MIBs
- Remove obsolete :mib_dir (singular) config
- MIB files are now part of the release and included in Docker image
- Paths work in both development and production environments
