glib: add compatibility implementation for g_dir_make_tmp()
We're going to make use of g_dir_make_tmp() in test-logging. Provide a compatibility implementation of it for glib < 2.30. May behave differently in some edge cases (e.g. pattern only at the end of the template, the file name is not part of the error message), but good enough in practice.
