`resolv_gethostbyname_dns_parse()` didn't use `status` and it was
always set to `ARES_SUCCESS` anyway.

instead of deprecated `ares_parse_a/aaaa/_reply()`

This patch doesn't replace `ares_parse_srv_reply()` as benefints
are quite questionable.

Partially resolves SSSD#7571

In theory new API might be somewhat better.

But:

1) it's fairly new: `ares_search_dnsrec()` and `ares_query_dnsrec()`
were introduced in c-ares-1.28 while even CentOS Stream 10 has
c-ares-1.25, so SSSD would need to support (fallback) old API anyway.

2) SSSD doesn't make heavy use of DNS, so potential performance
improvements are really negligible.

On the other hand, old API/ABI will be available for a long time:
c-ares/c-ares#732 (comment)

For those reasons it's not worth the effort to port code to new API
right now.
