Subject: [PATCH] unbound: create extra host records from DHCP static leases

The "Extra DNS" option allows to create records from the DHCP
"Hostnames" configuration entries.
This allows to create such records from the DHCP "Static leases"
configuration entries too.

Fixes: #22593

Signed-off-by: Julien Cassette <julien.cassette@gmail.com>
(cherry picked from commit b4a31f92deb8de923d6bc6fb12506e24f4475581)
