Qt4ProjectManager: Small refactoring in reportIssues

Do not report project dir specific issues next to each
buildconfiguration. Also move the code to a place the TargetSetupPage
can easily use, without having a hardcoded target list. Note: They
currently aren't shown at all, next step is to show them once per
target.
