[PATCH] linux: Define STAT64_IS_KERNEL_STAT64 by default

[Stafford Horne]

In commit 36260d5035 ("linux: Set default kernel_stat.h to LFS") the
default for STAT64_IS_KERNEL_STAT64 was removed.  This patch adds it
back.

For architectures that want to used the default kernel_stat.h and do not
have __NR_newfstatat, STAT64_IS_KERNEL_STAT64 needs to be defined.  Set
the default as 1 as modern port's stat64 struct should match the kernel
stat64 layout.

I tested this on the OpenRISC port and it seems to work fine.  Currently,
all archs that use the default kernel_stat.h define __NR_newfstatat so
they will not use the STAT64_IS_KERNEL_STAT64 macro.  However, arc seems
to be an outlier it uses the default kernel_stat.h, but does not define
__NR_newfstatat or __NR_fstatat64 I am not clear how arc works here.
