perf symbols: Check symbol_conf.allow_aliases for kallsyms loading too We can allow aliases to be kept, but we were checking this just when loading vmlinux files, be consistent, do it for any symbol table loading code that calls symbol__fixup_duplicate() by making this function check .allow_aliases instead.
