Kernel+LibC: Add a dbgputch() syscall and use it for userspace dbgprintf().
The "stddbg" stream was a cute idea but we never ended up using it in practice, so let's simplify this and implement userspace dbgprintf() on top of a simple dbgputch() syscall instead. This makes debugging LibC startup a little bit easier. :^)
