od: linux_defconfig: Remove debug options

We enable `CONFIG_EMBEDDED`, which selects `CONFIG_EXPERT`. `CONFIG_EXPERT` selects `CONFIG_DEBUG_KERNEL`, which enables several kernel debugging options by default. This commit disables them. I thought of disabling `CONFIG_EMBEDDED` instead because we do not use it for anything but we do need `CONFIG_EXPERT` for `LD_DEAD_CODE_DATA_ELIMINATION` anyway. rg99 comparison (`dmesg | grep Memory`): ``` - Memory: 23616K/32768K available (4150K kernel code, 610K rwdata, 604K rodata, 1216K init, 274K bss, 7104K reserved, 2048K cma-reserved) + Memory: 23664K/32768K available (4126K kernel code, 606K rwdata, 600K rodata, 1248K init, 238K bss, 7056K reserved, 2048K cma-reserved) ``` Signed-off-by: Gleb Mazovetskiy <[email protected]>
