TOMOYO: Accept manager programs which do not start with / .
The pathname of /usr/sbin/tomoyo-editpolicy seen from Ubuntu 12.04 Live CD is squashfs:/usr/sbin/tomoyo-editpolicy rather than /usr/sbin/tomoyo-editpolicy . Therefore, we need to accept manager programs which do not start with / . Signed-off-by: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> Signed-off-by: James Morris <james.l.morris@oracle.com>
