    syswrap, i386-linux: add missing ipc syscalls
    
    Kernel 5.1 introduced separate IPC syscalls:
    * semget
    * semctl
    * shmget
    * shmctl
    * shmat
    * shmdt
    * msgget
    * msgsnd
    * msgrcv
    * msgctl
    
    instead of ipc()
    
    Note the new shm wrappers were already added as
    afea9317a1c9 ("Bug 501846 - Add x86 Linux shm wrappers")
