NEWS: add description for DHCPv6 SIP feature

Also move the description of IPv4DuplicateAddressDetectionTimeoutSec=
to the section about systemd-networkd. The change of the timeout doesn't
have to be described as "incompatible". It's more of a bugfix, the previous
timeout was just strangely large and hopefully nobody relied on this detail
of implementation.

Also, reword to say that MPLSRouting= just controls enablement, nothing more.
