Fix log message when multiple tors try the same data directory
When a user launches two tor processes in the same data directory, they get these confusing logs:
Mar 29 17:45:08.000 [warn] It looks like another Tor process is running with the same data directory. Waiting 5 seconds to see if it goes away. Mar 29 17:45:13.000 [err] No, it's still there. Exiting. Mar 29 17:45:13.000 [err] set_options(): Bug: Acting on config options left us in a broken state. Dying. (on Tor 0.4.2.7 ) Mar 29 17:45:13.000 [err] Reading config failed--see warnings above. Mar 29 19:55:41.000 [notice] Catching signal TERM, exiting cleanly.
I don't think the bug log should be there.
