test(integration): add SysV shm tracing coverage
The SysV shared-memory family (shmget/shmat/shmdt/shmctl) had no
end-to-end integration coverage. Add an ioworkload `sysv-shm-basic`
scenario that, without privileges, runs shmget(IPC_PRIVATE) -> shmat ->
write into the mapped segment -> shmdt -> shmctl(IPC_RMID), always
issuing IPC_RMID (via defer) so no kernel segment leaks.
Add TestSysVShmBasic asserting enter_shmget/enter_shmat/enter_shmdt/
enter_shmctl are each traced with a positive (paired enter/exit)
duration.
msg/sem coverage is scoped out and tracked as a follow-up task (7i0).
