selinux: quiet the filesystem labeling behavior message

While the filesystem labeling method is only printed at the KERN_DEBUG level, this still appears in dmesg and on modern Linux distributions that create a lot of tmpfs mounts for session handling, the dmesg can easily be filled with a lot of "SELinux: initialized (dev X ..." messages. This patch removes this notification for the normal case but leaves the error message intact (displayed when mounting a filesystem with an unknown labeling behavior).
