fngsystem: remove output from fbcon, cleanup bootlog
To have a clean bootlogo we normally don't want any output on the framebuffer console. Make sure the known output is send to the serial console. Disable getty on the fbcon. Cleanup the output a little. Stop bootlogd, as it prints the content to fbcon.
