hadrian: Reduce default verbosity

This change reduces the default verbosity of error messages to omit the
stack trace information from the printed output.

For example, before all errors would have a long call trace:

```
Error when running Shake build system:
  at action, called at src/Rules.hs:39:19 in main:Rules
  at need, called at src/Rules.hs:61:5 in main:Rules
* Depends on: _build/stage1/lib/package.conf.d/ghc-9.3.conf
* Depends on: _build/stage1/compiler/build/libHSghc-9.3.a
* Depends on: _build/stage1/compiler/build/GHC/Tc/Solver/Rewrite.o
* Depends on: _build/stage1/compiler/build/GHC/Tc/Solver/Rewrite.o _build/stage1/compiler/build/GHC/Tc/Solver/Rewrite.hi
  at cmd', called at src/Builder.hs:330:23 in main:Builder
  at cmd, called at src/Builder.hs:432:8 in main:Builder
* Raised the exception:
```

Which can be useful but it confusing for GHC rather than hadrian
developers.
