kprobes: remove dependency on CONFIG_MODULES
kprobes depended on CONFIG_MODULES because it has to allocate memory for
code.
Since code allocations are now implemented with execmem, kprobes can be
enabled in non-modular kernels.
Add #ifdef CONFIG_MODULE guards for the code dealing with kprobes inside
modules, make CONFIG_KPROBES select CONFIG_EXECMEM and drop the
dependency of CONFIG_KPROBES on CONFIG_MODULES.
