semctl: fix indirect syscall decoding

On architectures where the semctl call is implemented by the ipc syscall
the 4th argument is passed by reference.

* ipc.c (sys_semctl): Handle the indirect ipc subcall case.
* tests/ipc_sem.c (main): Optionally match indirection
in the 4th argument of semctl calls.
