Currently, the loops in layout_symtab() and add_kallsyms() duplicate the

symbol table.
Rename is_core_symbol() to is_kept_symbol() and move the entire checking
logic inside it, including the special handlers for the first symbol and
livepatch modules.
No functional change.

Looks ok to me. I'm also fine also keeping the current name,
is_core_symbol(), as Huacai mentions in his review [1]. I previously
suggested is_kept_symbol() [2], since the is_livepatch_module() check
is moved into this function. However, is_core_symbol() is still ok, as
it is consistent with where the symbols are assigned, in
module::core_kallsyms.
OK, let me use is_core_symbol() in v4.
The important part is to avoid duplicating the checks that determine
whether a symbol should be kept in layout_symtab() and add_kallsyms().
