perf symbols: Check symbol_conf.allow_aliases for kallsyms loading too

Browse Source 
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.
