Kernel: Make all syscall functions return KResultOr<T>

This makes it a lot easier to return errors since we no longer have to
worry about negating EFOO errors and can just return them flat.

Kernel+LibC+UserspaceEmulator: Bring back sys$dup2()

This is racy in userspace and non-racy in kernelspace so let's keep
it in kernelspace.

The behavior change where CLOEXEC is preserved when dup2() is called
with (old_fd == new_fd) was good though, let's keep that.
