dns/knot-resolver: upgrade to 5.7.0

ChangeLog: https://www.knot-resolver.cz/2023-08-22-knot-resolver-5.7.0.html

Security

• avoid excessive TCP reconnections in a few more cases Like before, the remote server had to behave nonsensically in order to inflict this upon itself, but it might be abusable for DoS.

Improvements

• forwarding mode: tweak dealing with failures from forwarders, in particular prefer sending CD=0 upstream

Bugfixes

• fix unusual timestamp format in debug dumps of records
• adjust linker options; it should help less common platforms
• hints module: fix names inside home.arpa.
• EDNS padding (RFC 8467) compatibility with knot-dns 3.3 libs
