[PATCH] installer: suppress kernel warning/info/debug messages

['Badrikesh Prusty' via isar-users]

Lower the kernel log level to 3 to suppress warning, 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.
