TOMOYO: Accept \000 as a valid character.
commit 25add8cf99c9ec8b8dc0acd8b9241e963fc0d29c upstream. TOMOYO 2.5 in Linux 3.2 and later handles Unix domain socket's address. Thus, tomoyo_correct_word2() needs to accept \000 as a valid character, or TOMOYO 2.5 cannot handle Unix domain's abstract socket address.
