linux: Set LFS statfs as default

Currently glibc has three different struct statfs{64} definitions:

  1. Non-LFS support where non-LFS and LFS struct have different
     size: alpha, arm, hppa, i686, m68k, microblaze, mips (all abis),
     powerpc32, s390, sh4, and sparc.

  2. Non-LFS support where non-LFS and LFS struct have the same
     size: csky and nios2.

  3. Only LFS support (where both struct have the same size): arc,
     ia64, powerpc64 (including LE), riscv (both 32 and 64 bits),
     s390x, sparc64, and x86 (including x32).

The STATFS_IS_STATFS64/__STATFS_MATCHES_STATFS64 does not tell apart
between 1. and 2. since for both the only difference is the struct
size (for 2. both non-LFS and LFS uses the same syscall, where for
1. the old non-LFS is used for [f]statfs).

This patch move the generic statfs.h for both csky and nios2, and
make the default definitions for newer ABIs to assume that only
LFS will be support (so there is no need to keep no-LFS and LFS
struct statfs with the same size, it will be implicit).

This patch does not change the code generation.
