bind: upgrade 9.18.20 -> 9.18.21

bind-ensure-searching-for-json-headers-searches-sysr.patch
refreshed for 9.18.21

Changelog:
==========
-Improve LRU cleaning behaviour.
-The "resolver-nonbackoff-tries" and "resolver-retry-interval" options are
 deprecated; a warning will be logged if they are used.
-BIND might sometimes crash after startup or re-configuration when one 'tls'
 entry is used multiple times to connect to remote servers due to initialisation
 attempts from contexts of multiple threads. That has been fixed.
-Dig +yaml will now report "no servers could be reached" also for UDP setup
 failure when no other servers or tries are left.
-Recognize escapes when reading the public key from file.
-Dig +yaml will now report "no servers could be reached" on TCP connection
 failure as well as for UDP timeouts.
-Deprecate AES-based DNS cookies.
