Currently when assigning IPv6 addresses with large prefixes to a wireguard
interface, like

    config interface 'wg'
            option proto 'wireguard'
            list addresses 'fd::/48'

and having, say, a LAN interface such as

    config interface 'lan'
            option proto 'static'
            option ip6assign '60'

as is default the interface does not automatically receive the wg
interface's prefix.

For this to happen the proto needs to use proto_add_ipv6_prefix to register
the fact that a prefix is available for assignment which is simple enough.

v4: Remove note about netifd incompatibility as master already has the fix.
