tst_safe_sysv_ipc: Make safe_shmctl() and safe_msgctl() safer

We recently had a regression in Sys V IPC when IPC_STAT returned
non-zero integer on success wrongly, which wasn't caught by LTP test but
breaks software in the wild.

This commit changes safe_shmctl() and safe_msgctl() to check the return
value with != 0 for IPC_STAT, IPC_SET and IPC_RMID and with == -1
otherwise.
