dns/knot3: upgrade to 3.2.7

ChangeLog: https://www.knot-dns.cz/2023-06-06-version-327.html

Features:

• knotd: new configuration option for preserving incoming IXFR changeset history (see 'zone.ixfr-by-one')

Improvements:

• knotd: journal ensures the stored changeset's SOA serials are strictly increasing
• knotd: more effective handling of zero KNOT_ZONE_LOAD_TIMEOUT_SEC environment value
• knotd, kdig: incoming transfer fails if a message has the TC bit set
• knotd, kjournalprint: store or print the timestamp of changeset creation
• kxdpgun: load only necessary number of queries (Thanks to Petr Špaček)
• kxdpgun: print ratio of sent vs. requested queries (Thanks to Petr Špaček)
• kxdpgun: print percentages as floats (Thanks to Petr Špaček)
• kjournalprint: ability to print a changeset loop
• kjournalprint: added changset serials information to '-z -d' output
• packaging: RHEL9 requires libxdp like fedora since RHEL 9.2
• doc: various improvements

Bugfixes:

• knotd: journal loading can get stuck in a multi-changeset loop
• knotd: missing RCU lock when reading zone through the control interface
• knotd: server start D-Bus signaling doesn't work well if the zone file is missing, catalog zones are used, or in the async-start mode
• knotd: test suite fails on 32bit architectures on musl 1.2 and newer
• knotd: failed to process zero-length messages over QUIC
• libs: compilation with embedded ngtcp2 fails if there is another ngtcp2 in the path
