Subject: [PATCH] iv: drop

iv was only used as a dependency for neuron. The last neuron version
that used iv was 7.7, so when updating neuron to 8.2.1 in
77aed400272819132e4eeccd9b4bc7aa61c901b6 iv was made obsolete. It
continued building (with an incorrect URL due to an unchanged hash) up
until December 2024. Now the time has come for iv to be dropped.
