kallsyms: Make module_kallsyms_on_each_symbol generally available

Browse source 
commit 73feb8d5fa3b755bb51077c0aabfb6aa556fd498 upstream.

Making module_kallsyms_on_each_symbol generally available, so it
can be used outside CONFIG_LIVEPATCH option in following changes.

Rather than adding another ifdef option let's make the function
generally available (when CONFIG_KALLSYMS and CONFIG_MODULES
options are defined).
