[Buildroot] [git commit branch/2021.02.x] package/c-ares: security bump to version 1.17.2

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=1d18c730bb6084b2158f6cc8d185f4b3cd9b527f
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2021.02.x

- NodeJS passes NULL for addr and 0 for addrlen to
  ares_parse_ptr_reply() on systems where malloc(0) returns NULL. This
  would cause a crash.
- If ares_getaddrinfo() was terminated by an ares_destroy(), it would
  cause a 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 follow-up
- Perform validation on hostnames to prevent possible XSS due to
  applications not performing valiation themselves
