LTP testing: msgctl/IPC_STAT

[Johannes Stezenbach <js@convergence.de>]

I was investigating LTP test suite failures of the msgctl01,
msgctl02, msgsnd01 and msgsnd02 tests. It seems that they
are caused by a mismatch between /usr/include/bits/msq.h
and linux/include/asm-mips/msgbuf.h.

I suggest the following patch which makes mips' msgbuf.h
a copy of the one in include/asm-i386.
