Bring target_flock definitions to be more in sync with the way flock is defined in kernel. Basically, the rules from the kernel are: 1. Majority of architectures have a common flock definition. 2. Architectures with 32-bit MIPS ABIs have a sligtly different flock definition; those architectures are the only arcitectures that have HAVE_ARCH_STRUCT_FLOCK defined, and that preprocessor constant is used in the common header as a flag for including or not including common flock definition. 3. Sparc architectures also have a sligtly different flock definition, but the difference is only the padding at the end of the structure. The presence of that padding is determined by preprocessor constants __ARCH_FLOCK6_PAD and __ARCH_FLOCK64_PAD. QEMU linux-user already implements rules 1. and 3. in a very similar way as they are implemented in kernel. However, rule 2. is implemented in a dissimilar way (for example, the constant TARGET_HAVE_ARCH_STRUCT_FLOCK is missing), and this patch brings QEMU implementation much closer to the kernel implementation. TARGET_HAVE_ARCH_STRUCT_FLOCK64 constant is also introduced to mimic HAVE_ARCH_STRUCT_FLOCK64 from kernel, but it is not defined anywhere, however, this is the case with HAVE_ARCH_STRUCT_FLOCK64 in kernel as well.
