linux: Define STAT64_IS_KERNEL_STAT64

Browse Source 
It indicates that the glibc export stat64 is similar in size and
layout of the kernel stat64 used on the syscall.  It is not currently
used on stat implementation, but the idea is to indicate whether
to use the kernel_stat to issue on the syscall on the *stat*64
variant (more specifically on mips which its exported ABI does not
match the kernel).
