selftests/ipc: Fix msgque compiler warnings

commit a147faa96f832f76e772b1e448e94ea84c774081 upstream.

This fixes the various compiler warnings when building the msgque
selftest. The primary change is using sys/msg.h instead of linux/msg.h
directly to gain the API declarations.

Fixes: 3a665531a3b7 ("selftests: IPC message queue copy feature test")
