Subject: [PATCH] RISC-V: Include clone3() on rv32

From: Palmer Dabbelt <palmerdabbelt@...gle.com>

As far as I can tell this should be enabled on rv32 as well, I'm not
sure why it's rv64-only.  checksyscalls is complaining about our lack of
clone3() on rv32.

Fixes: 56ac5e213933 ("riscv: enable sys_clone3 syscall for rv64")
