r320: Fixed a rather esoteric bug: If a file had multiple hard links, and was
suid, suidregister detected all the hard links as files that need to be registered. It looped, registering the first link, and then removing its suid bit. This messed up the registration of the other had links, since their permissions were now changed, leading to unpredictable results. The fix is to just not remove suid bits until all files have been registered.
