Update to 1.24.2

- Fixes CVE-2025-11411

Features from 1.24:

- Increase default to `num-queries-per-thread: 2048`
- num.valops in extended statistics
- unbound-control cache_lookup <domains> support
- zone status for auth-zones

Features from 1.23:

- Increase the default of max-global-quota to 200 from 128
- The default value of serve-expired-client-timeout is set to 1800
- Support for RESINFO RRType 261 (RFC9606).
- Add resolver.arpa and service.arpa to the default locally served zones.
- Fast Reload. The unbound-control fast_reload is added.
- DNS Error Reporting (RFC 9567).

Features from 1.22:
- Add iter-scrub-ns, iter-scrub-cname and max-global-quota configuration options.
- Merge patch to fix for glue that is outside of zone, with `harden-unverified-glue`
- log timestamps in ISO8601 format with timezone
- DNS over QUIC. This adds `quic-port: 853` and `quic-size: 8m`.
  Requires ngtcp2, not yet in RHEL.

Features from 1.21:
- Clear both in-memory and cachedb module cache with `unbound-control flush*` commands.
- Add dnstap-sample-rate that logs only 1/N messages.
- Add root key 38696 from 2024 for DNSSEC validation.
- Cookie secret file. Adds `cookie-secret-file option.

And a lot of bug fixes.

Subject: [PATCH] Add unbound members group access to control key
Recent openssl genrsa does not use umask for generated keys. There is no
strong reason why every member of unbound group should be able read
server key. But control key would be quite useful to be group readable
and to allow control access to whole group. Allowing access to control
by group membership, not via sudo.
