[PRQ#72842] Deletion Request for ros-noetic-ecl-build

MarsSeed [1] filed a deletion request for ros-noetic-ecl-build [2]: Defunct, unused, EOL package from 2020. ROS1 Noetic is reaching its EOL too, and the majority of its libraries are no longer compatible with Arch Linux, only with Python 3.9 and the already EOL Ubuntu 20.04 and Qt 5.12.
