refactor(build): Simplify Dockerfile and entrypoint.sh scripts for VNyanNet installation

Changes made in Dockerfile:
- Removed winbind from dependencies
- Added rsync to copy files into the correct directory

Changes made in entrypoint.sh:
- Simplified copying of files into the bin directory
- Removed unnecessary mkdir commands for CONFIG_DIR
- Changed the configuration file path to be within the bin directory

These changes should help simplify the installation process, reducing potential errors and improving maintainability.
