[PRQ#53522] Deletion Request for libad9361-iio-git

dreieck [1] filed a deletion request for libad9361-iio-git [2]: This is obsolete since IIO is included in mainline gnuradio as stated at https://wiki.analog.com/resources/tools-software/linux- software/gnuradio#gnu_radio_37, and no other package than `gnuradio- iio-git` depends on it.
