Buildroot update

* Updated buildroot
* Removed sd-lldp.patch for the old systemd, replaced with systemd's
  pull request #20333 [1]
* Added updated velia that works with the new systemd patch.
* Updated velia dependencies as we now require nlohmann/json
  (json-for-modern-cpp)
* Updated netconf-cli because we need new code that fixes build against
  boost 1.77 [2]
