hadrian: Reduce Cabal verbosity

The comment claims that `simpleUserHooks` decrease verbosity, and it
does, but only for the `postConf` phase. The other phases are too
verbose with `-V`.

At the moment > 5000 lines of the build log are devoted to output from
`cabal copy`.

So I take the simple approach and just decrease the verbosity level
again.

If the output of `postConf` is essential then it would be better to
implement our own `UserHooks` which doesn't decrease the verbosity for
`postConf`.

Fixes #24338
