Missing IPv6 addresses - only link local displayed

[tlstpierre]

The networkInterfaces function shows IPv6 address information, but only the first IPv6 address, which seems to be link-local (the least useful address).

This function should return all IPv6 addresses as an array, or at the very least, return the first non-link-local address. The link-local address probably should be in a different field, or perhaps omitted, since you can calculate it from the MAC anyway.

To reproduce:

-Call the function and log the output on a computer with working IPv6
-Compare the output with the network configuration using ifconfig, ipaddr, or another mechanism to view your network config.
-Notice that only the link local (fe80) address is present, not the globally-unique addresses.

For example:
{
iface: 'en6',
ifaceName: 'en6',
default: true,
ip4: '172.17.16.146',
ip4subnet: '255.255.255.0',
ip6: 'fe80::e:379d:7f60:33a3',
ip6subnet: 'ffff:ffff:ffff:ffff::',
mac: 'a0:ce:c8:5f:7e:73',
internal: false,
virtual: false,
operstate: 'up',
type: 'wired',
duplex: 'full',
mtu: 1500,
speed: 1000,
dhcp: true,
dnsSuffix: '',
ieee8021xAuth: '',
ieee8021xState: '',
carrierChanges: 0
}

Tested on Mac OS 12.7.6

Expected behaviour is that the function can return all IPv6 addresses, especially the non-link-local addresses. The 2001:db8: addresses (normally would be 2xxx:xxxx, but 2001:db8 is the IPv6 example prefix) are the ones the computer uses to communicate outside of the network, so knowing this is typically what one would want to find.
