T8599: Don't ignore other build.py failures

Exit with error for other failures:

* Creating/installing dependency package should be error: e.g. debugging
  why strongswan cannot find systemd could be easier if build.py failed
  when it couldn't install systemd and not when `configure` couldn't
  find it.
* Creating tarball
* pre_hook run
