linux-user: Fix target_flock structure for MIPS O64 ABI

Browse Source 
Among MIPS ABIs, only MIPS O32 and N32 have special (different
than other architectures) definition of structure flock in kernel.

Bring target_flock definition in QEMU for MIPS O64 ABI to the
correct state, which is currently different than the most common
definition, and it should actually be the same.
