The fcntl F_GETLK64/F_SETLK64/F_SETLKW64 are only implemented for the
32-bit syscall APIs, but we also need them for compat handling on 64-bit
builds. Redefining them is error prone (as shown by the example that
parisc gets it wrong currently), so we should use the same defines for
both case. In theory we could try to hide them from userspace, but
given that only MIPS actually gets that right, while the asm-generic
version used by most architectures relies on a Kconfig symbol that can't
be relied on to be set properly by userspace is a clear indicator to not
bother.
