Documentation: refer to config RANDOMIZE_BASE for kernel address-space randomization

Browse Source 
The config RANDOMIZE_SLAB does not exist, the authors probably intended to
refer to the config RANDOMIZE_BASE, which provides kernel address-space
randomization. They probably just confused SLAB with BASE (these two
four-letter words coincidentally share three common letters), as they also
point out the config SLAB_FREELIST_RANDOM as further randomization within
the same sentence.

Fix the reference of the config for kernel address-space randomization to
the config that provides that.

Using kernel address space randomization (CONFIG_RANDOMIZE_SLAB=y
Using kernel address space randomization (CONFIG_RANDOMIZE_BASE=y
and CONFIG_SLAB_FREELIST_RANDOM=y in the kernel configuration) makes
attacks on the kernel generally more difficult.
