Fix memleaks related to get_dirname
get_dirname may return NULL instead of the original string, so avoid
patterns like get_dirname(strdup(x)). Writing to
cf_path.toUtf8().data() is fine btw, toUtf8() returns new memory.
This fixes two memleak reported by LeakSanitizer via fileset_add_dir and
MainWindow::captureFileReadFinished (both via cf_callback_invoke).
