linux: Set default kernel_stat.h to LFS

Browse Source 
The XSTAT_IS_XSTAT64 and STAT_IS_KERNEL_STAT flags are now set to 1 and
STATFS_IS_STATFS64 is set to __STATFS_MATCHES_STATFS64.  This makes the
default ABI for newer ports to provide only LFS calls.

A copy of non-LFS support is provided to 32-bit ABIS with non-LFS
support (arm, csky, i386, m68k, nios2, s390, and sh).  Is also allows
to remove the 64-bit ports, which already uses the default values.

This patch does not change the code generation.
