make deploy location configurable

Allow specifying custom deployment directory as argument, defaulting to
/opt/jrunner if not provided. Symlink to /usr/local/bin only created
for default location to avoid overwriting production.

Usage:
  ./deploy.sh                    # deploys to /opt/jrunner (default)
  ./deploy.sh /opt/jrunner-test  # test deployment

This allows testing new builds without affecting production deployment.
