Andreas Kling 3fce2fb205 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. :^)
