Fix for bug 76183 and bug 71555: consolidates chmod activity in one place in checksetup.pl and also provides permission setting for bugzilla installations installed in a personal user directory as opposed to the server's main web space. (makes the files world-readable so the webserver can see them, since you can't set the group)
