kprobe: move sysctl_kprobes_optimization to kprobes.c
kernel/sysctl.c is a kitchen sink where everyone leaves their dirty
dishes, this makes it very difficult to maintain.
To help with this maintenance let's start by moving sysctls to places
where they actually belong. The proc sysctl maintainers do not want to
know what sysctl knobs you wish to add for your own piece of code, we
just care about the core logic.
Move sysctl_kprobes_optimization from kernel/sysctl.c to
kernel/kprobes.c. Use register_sysctl() to register the sysctl
interface.
