Log Message:
net/powerdns-recursor: Update to 4.3.4

Changelog for 4.3.4:
Released: 8th of September 2020
* Improvements:
  - Ensure runtime dirs for virtual services differ.

* Bug Fixes:
  - Allow some more depth headroom for the no-qname-minimization fallback case
  - Resize hostname to final size in getCarbonHostname().

Changelog for 4.3.3:
Released: 17th of July 2020
* Bug Fixes:
  - Validate cached DNSKEYs against the DSs, not the RRSIGs only.
  - Ignore cache-only for DNSKEYs and DS retrieval.
  - A ServFail while retrieving DS/DNSKEY records is just that.
  - Refuse DS records received from child zones.
  - Better exception handling in houseKeeping/handlePolicyHit.
  - Take initial refresh time from loaded zone.

pkgsrc-specific changes:
  - Move pdns socket directory to /var/run/pdns-recursor
    to reduce diff
  - Introduce SMF method script that also creates the
    socket directory on platforms where /var/run is not
    persistent (i.e. swap or tmpfs-mounted)
