linux-user: Fix TARGET_F_GETOWN definition for Mips

For some reason, Qemu's TARGET_F_GETOWN constant for Mips does not
match the correct value of correspondent F_GETOWN. This patch fixes
this problem.

For reference, see Mips' F_GETOWN definition in Linux kernel at
arch/mips/include/uapi/asm/fcntl.h#L44.

This patch also fixes some fcntl()-related LTP tests for Qemu
user mode for Mips.
