riscv: add asm/unistd.h UAPI header

Marcin Juszkiewicz reported issues while generating syscall table for riscv
using 4.20-rc1. The patch refactors our unistd.h files to match some other
architectures.

- Add asm/unistd.h UAPI header, which has __ARCH_WANT_NEW_STAT only for 64-bit
- Remove asm/syscalls.h UAPI header and merge to asm/unistd.h
- Adjust kernel asm/unistd.h

So now asm/unistd.h UAPI header should show all syscalls for riscv.

Before this, Makefile simply put `#include <asm-generic/unistd.h>` into
generated asm/unistd.h UAPI header thus user didn't see:

- __NR_riscv_flush_icache
- __NR_newfstatat
- __NR_fstat

which are supported by riscv kernel.
