[01/10] linux: Fix STATFS_IS_STATFS64 definition

aarch64, arc, ia64, mips64, powerpc64, riscv32, riscv64, s390x, sparc64,
and  x86_64 defines STATFS_IS_STATFS64 to 0, but all of them alias
both statfs to statfs64 and struct statfs has the same and layout of
struct statfs64.

The correct definition will be used on the {f}statfs{64} consolidation.

This patch does not change code generation since the symbols are
implemented using the auto-generation syscall for all the aforementioned
abis.

This is sane. LGTM.
