On Rawhide Cloud_Base boots, there's some SSH key and network
information printed above the 'login:' prompt, so we can't
expect empty space there. Also tweak console_login() to clear
the screen after logging in, so the login prompt is cleared and
doesn't confuse things on subsequent runs (like it did first
time we tried this). And add a new user logged in needle, as it
seems after we clear the screen the tilde appears in a slightly
different position and the existing needle doesn't match.
