linux: Enable SLAB_FREELIST_HARDENED, SLAB_FREELIST_RANDOM
Enabled in [Arch][1], [Debian][2], [Fedora][3]; no others checked.
Recommended by [Kernel Self Protection Project][4]. This should also
implicitly enable SHUFFLE_PAGE_ALLOCATOR.
Performance impact per upstream:
For _HARDENED:
> The difference gets lost in the noise, but if the above is to be taken
> literally, using CONFIG_FREELIST_HARDENED is 0.07% slower.
For _RANDOM:
> Performance results highlighted no major changes
