    generic: keep module aliases inside .modinfo
    
    It seems module aliases are actually essential info.  E.g. other modules
    may call xt_request_find_match(NFPROTO_IPV{4,6}, "hashlimit", 1) and the
    kernel will request user mode modprobe helper for ipt_hashlimit and
    ip6t_hashlimit respectively which are aliases of xt_hashlimit.ko
    
    Compile-tested for armvirt, there is nearly no size impact.
