ipc: Fix building compat mode without sysvipc

Browse Source 
As John Stultz noticed, my y2038 syscall series caused a link
failure when CONFIG_SYSVIPC is disabled but CONFIG_COMPAT is
enabled:

arch/arm64/kernel/sys32.o:(.rodata+0x960): undefined reference to `__arm64_compat_sys_old_semctl'
arch/arm64/kernel/sys32.o:(.rodata+0x980): undefined reference to `__arm64_compat_sys_old_msgctl'
arch/arm64/kernel/sys32.o:(.rodata+0x9a0): undefined reference to `__arm64_compat_sys_old_shmctl'

Add the missing entries in kernel/sys_ni.c for the new system
calls.
