Explicitly return `ENOSYS` for the `clonefileat` and `fclonefileat` syscalls
We were already returning ENOSYS in `__unknown_syscall`, but that prints a message saying the syscall is unimplemented.
This version is a valid implementation of the syscalls (it's not guaranteed to be available on all systems).
