deps: cherry-pick 0d252eb from upstream c-ares

Original commit message:

  If there are more ttls returned than the maximum provided by the requestor, then
  the *naddrttls response would be larger than the actual number of elements in
  the addrttls array.

  This bug could lead to invalid memory accesses in applications using c-ares.

  This behavior appeared to break with PR https://github.com/c-ares/c-ares/pull/257
