4.4 downgrade of arbiter should delete the arbiter data directory as we did for 4.2 downgrade.

Description of Linked Ticket
Arbiters don't track FCV so they won't remove the configTerm from their on disk ReplSetConfig object on downgrade. This causes a 4.2 node to fail parsing of the config on restart after binary downgrade.
