function ModuleUpdater::getInstallDirectory

Return the directory where a module should be installed.

If the module is already installed, drupal_get_path() will return a valid path and we should install it there (although we need to use an absolute path, so we prepend DRUPAL_ROOT). If we're installing a new module, we always want it to go into sites/all/modules, since that's where all the documentation recommends users install their modules, and there's no way that can conflict on a multi-site installation, since the Update manager won't let you install a new module if it's already found on your system, and if there was a copy in sites/all, we'd see it.
