Add a smoke test of erts_debug:df/1
Run erts_debug:df/1 for all loaded modules. On my reasonably fast, modern computer this test case runs in approximately 10 seconds. To avoid spending many minutes running this test case on older computers, limit the running time to 20 seconds. While we are at it, remove all ?line macros.
