From: Ilya Leoshkevich <iii@linux.ibm.com>
The indices of arguments used with semctl() are all off-by-1, because
arg1 is the ipc() command. Fix them. While at it, reuse print_semctl().
New output (for a small test program):
3540333 semctl(999,888,SEM_INFO,0x00007fe5051ee9a0) = -1 errno=14 (Bad
address)
Fixes: 7ccfb2eb5f9d ("Fix warnings that would be caused by gcc flag
-Wwrite-strings")
