[PRQ#44033] Deletion Request for libarsal-git

MarsSeed [1] filed a deletion request for libarsal-git [2]: This package was part of the ARDroneSDK3 for Parrot Drones. That SDK seems to have been silently discontinued after 2018-2019 [a], and now its official SDK documentation is also deleted. [b] Some of these packages have been broken since 2021 after Python2 components like virtualenv got deleted from repo. On AUR, all SDK3 related package are from 2016. It seems these are not used and usable anymore.
