linux-user: Fix structure target_semid64_ds definition for Mips

This patch corrects target_semid64_ds structure definition for Mips. See, for example definition of semid64_ds for Mips in Linux kernel: arch/mips/include/uapi/asm/sembuf.h#L13. This patch will also fix certain semaphore-related LTP tests for Mips, if they are executed in Qemu user mode for any Mips platform.
