Treat IPv6 link local addresses as loopback addresses.
IPv6 linklocal address are effectively loopback addresses because we don't expect to send traffic over them. Linux's getaddrinfo considers them "valid" with respect to AI_ADDRCONFIG, so we can't use that flag when there are only loopback *or* link local addresses configured.
BUG=55041
TEST=manually test that http://localhost/ works when link local addresses are configured.
