cmd/geth: drop upgradedb subcommand since it's unfeasible
This command was meant as a hackish way to upgrade our chain database way back when nobody cared for live updates and the size of the database along with its import times was small. With the current database weighing hundreds of GBs and processing times of many days, this command is just ludicrous.
