semctl01.c: Pass the correct parameter

For SEM_STAT, the semid argument is not a semaphore identifier,  but instead an
index into the kernel’s internal array that maintains information about all
semaphore sets on the system.

Pass a correct index of the kernel' internal array intead of a semaphores id when
testing feature SEM_STAT.
