  1. [ksyms] Do not cache ksyms to reduce memory consumption 

    We use ksyms for checking the proper exit hooks when loading the base
sensor. Furthermore, we use it when we add a kprobe policy for a
function that is part of a kernel module.

Having that always in memory, uses a lot of memory. This patch makes the
read of ksyms when we need that.
