zigbee: Revert /usr/bin installation to fix packaging error

- Remove attempt to install Zigbee apps to /usr/bin
- The base NXP SDK likely doesn't include zb_cli in the bin/ directory
- Keep existing functionality with simple_gw_zc in /usr/bin via zigbee-rcp-apps
- Avoids creating empty /usr/bin directory that causes packaging errors
