test: port IniHelperTest and RepositoryUtilsTest

IniHelper cases reach XdebugHandler::get_all_ini_files (todo!()); RepositoryUtils
filterRequiredPackages is fully modeled but building linked packages via
ArrayLoader parses constraints with a look-around regex the regex crate cannot
compile. Both ignored. setUp/tearDown not ported.
