is_loopback behaviour differs between ipv4 and ipv6 for IPNetwork

[Niels Keulen]

IPv4 behaviour:

>>> netaddr.IPAddress('127.0.0.1').is_loopback()
True
>>> netaddr.IPNetwork('127.0.0.1/32').is_loopback()
True

IPv6:

>>> netaddr.IPAddress('::1').is_loopback()
True
>>> netaddr.IPNetwork('::1/128').is_loopback()
False

I would expect all of the examples above to return True.
But as you can see netaddr.IPNetwork('::1/128').is_loopback() doesn't.

Tested on: 0.8.0
