hadrian: Increase verbosity of certain cabal commands

This is a hack to get around the cabal function we're calling
*decreasing* the verbosity it passes to another function, which is the
stuff we often actually care about. Sigh.

Keeping this a separate commit so if this makes things too verbose it is
easy to revert.
