Consolidate them in unistd.h instead of definining the internal compat definitions in compat.h, which is rather errror prone (e.g. parisc gets the values wrong currently). Note that before this change they were never visible to userspace due to the fact that CONFIG_64BIT is only set for kernel builds.
