artifact-armbian-bsp-cli: include BOOT_SOC in the bsp-cli hash

- This way we can safely include BOOT_SOC in /etc/armbian-release as done in the previous commit
- this will cause a rebuild of _all_ bsp-cli packages, even those for boards that don't define BOOT_SOC
- hopefully one day we will have BOOT_SOC ("What is the SoC?") defined for all boards
  - for now, it will be empty for those that don't define it, which should be harmless
