Subject: [PATCH 5/8] criu/dump: Fix size of personality buffer

Personality value is printed in kernel like this:

static int proc_pid_personality(/* .. */)

{

        int err = lock_trace(task);

        if (!err) {

                seq_printf(m, "%08x\n", task->personality);

                unlock_trace(task);

        }

        return err;

}

So, we don't need a whole page to read the value.
