Display all link IP addresses, on different lines

Currently, the "IP address" field in the status page of the
settings app displays only the IP addesses on the base link.
Make it display the stacked link IP addresses as well.

Also, separate IP addresses via newlines instead of commas.
For example, display:

2a00:f40:e000:11c:cf93:ee9:5ad3:6686
192.0.0.4

instead of:

2a00:f40:e000:11c:cf93:ee9:5ad3:6686, 192.0.0.4
