hadrian: Improve option parsing
Several options in Hadrian had their argument marked as optional
(`OptArg`), but if the argument wasn't there they were just giving an
error. It's more idiomatic to mark the argument as required instead;
the code uses less Maybes, the parser can enforce that the argument
is present, --help gives better output.
