test(integration): add SysV msg/sem tracing coverage
Add sysv-msg-basic and sysv-sem-basic ioworkload scenarios that exercise
the SysV message-queue and semaphore families end-to-end via raw syscalls,
mirroring the existing sysv-shm-basic scenario.
sysv-msg-basic: msgget(IPC_PRIVATE) -> msgsnd -> msgrcv -> msgctl(IPC_RMID),
using a struct msgbuf {int64 mtype; [16]byte mtext} and msgsz = body length
(excluding mtype). sysv-sem-basic: semget(IPC_PRIVATE, 1) -> semop(+1) ->
semop(-1) -> semctl(IPC_RMID), incrementing before decrementing so the
operation can never block. Both defer IPC_RMID right after the get so no
kernel IPC object leaks even on partial failure.
Add TestSysVMsgBasic and TestSysVSemBasic asserting the enter_ events for
msgget/msgsnd/msgrcv/msgctl and semget/semop/semctl are traced with
MinCount>=1 and positive duration, plus PID/comm hermetic guards.
