kernels: enable init_on_alloc by default 

https://cateee.net/lkddb/web-lkddb/INIT_ON_ALLOC_DEFAULT_ON.html

This will replace `slub_debug=P page_poison=1`. Only enabling
on x86, ARM and ppc64le for now and not ppc64/ppc because of
performance concerns on old hardware.

Not enabling init_on_free by default since that has a much larger
impact.
