    libi2pd: mark additional ipv6 addresses/nets as reserved

    This adds :: (undefined address), ::1 (loopback address) as well as
    ff00::/8 (multicast prefix) to reservedIPv6Ranges.

    A bunch of nodes seem to be publishing bogus addresses (mostly ::1)
    in the netDB, resulting in unnecessary tunnel build failures.
