The newer renameat2 syscall provides all the functionality provided by
the renameat syscall and adds flags, so future architectures won't need
to include renameat.

Therefore drop the renameat syscall from the generic syscall list unless
__ARCH_WANT_RENAMEAT is defined by the architecture's unistd.h prior to
including asm-generic/unistd.h, and adjust all architectures using the
generic syscall list to define it so that no in-tree architectures are
affected.

I just found this patch on an old branch, it appears to have slipped
through the cracks. Time for a respon.

Changes in v2:
- Rebase onto v4.6-rc5.
- Add __ARCH_WANT_RENAMEAT to h8300 and nios2 arches too.
