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.
