[PATCH] installer: suppress kernel info/debug messages

[Badrikesh Prusty]

Lower the kernel log level to 4 to suppress notice, info, and debug
messages on the console.
This prevents audit and driver messages from cluttering the screen
while keeping critical errors and systemd service status output
visible, resulting in a cleaner installer UI.
