Security update for c-ares
This update for c-ares fixes the following issues:
Version update to git snapshot 1.17.1+20200724:
- CVE-2021-3672: fixed missing input validation on hostnames returned by DNS servers (bsc#1188881)
- If ares_getaddrinfo() was terminated by an ares_destroy(), it would cause crash
- Crash in sortaddrinfo() if the list size equals 0 due to an unexpected DNS response
- Expand number of escaped characters in DNS replies as per RFC1035 5.1 to prevent spoofing
- Use unbuffered /dev/urandom for random data to prevent early startup performance issues
